You’ve probably done it without realising: bought something you didn’t need because it was on sale or spent extra to qualify for free delivery.
In your mind, you’re getting a bargain, but that’s usually not actually the case. This is a psychological trap known as “spaving”—a portmanteau that stands for spending to save—and it tricks your brain into thinking you’re being financially savvy while actually draining your wallet. Here’s why it’s not as great as it seems on the surface.
1. The free delivery trap actually costs you more.
Online retailers deliberately set free delivery thresholds just above your intended purchase to make you add unnecessary items to your basket. You end up spending £15 extra to avoid a £3.99 delivery fee, convincing yourself you’ve saved money when you’ve actually spent more than triple the shipping cost.
Track your actual spending versus what you originally planned to buy, and calculate whether paying for delivery would genuinely cost less. Most of the time, accepting the delivery charge and buying only what you need saves significant money compared to padding your order with items you don’t really want.
2. Buy one get one free creates unwanted stockpiling.
BOGOF deals manipulate you into buying double quantities of items you’d normally purchase occasionally, and perishable goods often go to waste before you can use them. Retailers use these offers to get rid of excess stock while making you feel like you’re getting incredible value.
Only take advantage of BOGOF deals for non-perishable items you genuinely use regularly and have storage space for. Calculate the per-unit cost against normal prices to ensure you’re actually saving money, and resist the psychological pressure to buy simply because something appears free.
3. Loyalty schemes encourage unnecessary spending.
Points-based loyalty programmes create artificial urgency by offering bonus rewards for reaching spending thresholds you wouldn’t naturally hit. You end up making purchases purely to earn points or maintain status levels, spending real money for rewards that often have limited value or complicated redemption processes.
Evaluate loyalty schemes based on your normal spending patterns rather than adjusting your purchases to maximise points. Calculate the actual cash value of rewards versus the extra spending required to earn them, and remember that the most loyal thing you can do for your finances is not overspending.
4. Bulk buying leads to waste and storage issues.
Warehouse stores and bulk deals convince you that buying larger quantities always saves money, but you often end up with more than you can reasonably use. Storage costs, spoilage, and the opportunity cost of tying up money in excess inventory frequently outweigh any per-unit savings.
Calculate the true cost per use rather than just per unit, factoring in how long items will last and whether you have appropriate storage space. Bulk buying only makes financial sense for non-perishable items you use consistently and have room to store properly without creating clutter or waste.
5. Flash sales create false urgency.
Limited-time offers and countdown timers trigger fear of missing out, pushing you to make quick decisions without proper consideration of whether you actually need the item. These psychological tactics exploit your brain’s tendency to prioritise immediate rewards over long-term financial goals.
Take a mandatory 24-hour cooling-off period before purchasing anything advertised as a limited-time deal, and research whether the “sale” price is genuinely discounted from normal retail prices. Many flash sales simply restore items to their regular price after artificially inflating them beforehand.
6. Credit card rewards justify overspending.
Cashback and rewards credit cards can encourage you to spend more to maximise benefits, turning what should be a passive reward into active overspending. The psychological satisfaction of earning rewards often overshadows the reality that you’re spending real money to earn pennies back.
Use reward cards only for purchases you’d make anyway, and pay off the full balance monthly to avoid interest charges that far exceed any rewards earned. Track your spending patterns before and after getting rewards cards to ensure you’re not unconsciously increasing your expenditure to chase points.
7. Subscription services auto-renew beyond usefulness.
Free trials and introductory offers for subscription services rely on you forgetting to cancel or assuming you’ll use them more than you actually do. Companies deliberately make cancellation processes complicated while offering “special deals” to keep you subscribed to services you rarely use.
Audit all your subscriptions monthly and cancel anything you haven’t used in the past 30 days, regardless of how good the deal seems or how much you might theoretically use it in future. Set calendar reminders before free trials end, and remember that you can usually resubscribe later if you genuinely need the service.
8. Discount codes inflate your basket size.
Percentage-off codes encourage you to add more items to increase your savings, and minimum spend requirements for discount codes push you beyond your original budget. Retailers strategically offer these codes to increase average order values while making customers feel smart about saving money.
Apply discount codes only to purchases you were already planning to make, and resist the temptation to add items simply to increase your percentage savings. Calculate whether the final price with added items and discount still exceeds what you would have spent originally without any code.
9. Seasonal sales exploit planning anxiety.
End-of-season clearances and pre-holiday sales convince you to buy items months before you need them, tying up money that could be earning interest or covering immediate expenses. The fear of items being unavailable or more expensive later often outweighs the actual financial benefit of early purchases.
Buy seasonal items only when you actually need them, and research historical pricing to understand whether “sale” prices represent genuine savings. The cost of storing items you won’t use for months, plus the opportunity cost of spending money early, often negates any discount received.
10. Membership fees create spending pressure.
Annual membership fees for shopping clubs and wholesale stores create psychological pressure to spend enough to justify the cost, leading to unnecessary purchases throughout the year. The sunk cost fallacy makes you feel obligated to shop at these stores, even when their prices aren’t actually better for your specific needs.
Calculate your annual spending at membership stores before renewing, and compare their prices against regular retailers for items you actually buy. Factor in travel costs and time spent shopping at these locations, and remember that paying a membership fee doesn’t guarantee savings if you don’t need the specific products they offer.
11. Bundle deals include unwanted extras.
Product bundles and package deals make you pay for items you don’t need while creating the illusion of comprehensive value and savings. Companies profit by including high-margin accessories or services alongside the main product you actually want, disguising the total cost as a bargain.
Price out bundle components individually to determine whether you’re actually saving money, and consider whether you genuinely need all the included items. Often, buying just the main product you want costs less than accepting a bundle with extras you’ll never use, even if the per-item price appears better.
12. Credit offers mask true spending costs.
Interest-free financing and “buy now, pay later” schemes disconnect the pain of payment from the pleasure of purchase, making expensive items feel more affordable than they actually are. These offers often include hidden fees and can damage your credit score if you miss payments or struggle with the deferred costs.
Calculate the total cost of credit purchases, including any fees, and ensure you can afford the full amount within the promotional period. Remember that interest-free doesn’t mean consequence-free, and spreading payments over time often leads to forgetting the true cost of items and overspending on other purchases.
13. Social media ads personalise false needs.
Targeted advertising uses your browsing history and personal data to present products as solutions to problems you didn’t know you had, creating artificial desires for items you’d never normally consider. The personalisation makes these ads feel like helpful recommendations rather than manipulative marketing tactics.
Unfollow shopping accounts and limit social media time during vulnerable moments like late-night browsing or stressful periods when you’re more susceptible to impulse purchases. Install ad blockers and regularly clear your browsing data to reduce the effectiveness of targeted marketing, and remember that algorithms profit from your spending, not your financial wellbeing.
