A large percentage beside a product does not tell you what you will actually save. Compare the exact item and the full checkout cost, then decide whether the offer fits your budget. The same method works for a student buying a laptop, a family comparing groceries or anyone shopping during a seasonal sale.
Check the reference price
Ask what a crossed-out “was” price represents. It may be an earlier selling price, a recommended price or another comparison figure. Look up the exact model at other reliable sellers and, if available, review its recent price history. Do not assume every crossed-out price was the normal price last week. The UK's Competition and Markets Authority warns that misleading price-reduction and urgency claims can pressure shoppers.
In India, a new rule helps here from 1 January 2027. Under the Consumer Protection (E-Commerce) (Amendment) Rules, 2026, a platform or seller that announces a price cut must also show the prior price, defined as the lowest price in the 30 days before the announcement. Until then, treat a crossed-out price as the seller's own claim. Even after it, check that the prior price is for the same variant and seller; our price-history guide explains how.
Compare like with like
Copy the full model number, storage size, warranty region and condition. A refurbished laptop, older phone variant or smaller pack is not directly comparable to a new item with the same marketing name. For groceries and essentials, compare the unit price as well as the pack price; UK price-marking guidance explains why unit prices help shoppers make comparable choices.
Calculate the total you must pay
Add unavoidable delivery, service and payment charges before comparing two sellers. For example, a £449 laptop with a required £15 delivery charge costs £464, more than a £455 laptop with free delivery. Check whether a card discount requires a minimum spend, a particular card, instalments or later cashback. Remove optional protection plans you did not choose. The US Federal Trade Commission's online-shopping guide also recommends checking model details, shipping fees, return rules and the full deal terms.
Pause when a page creates urgency
“Only two left” and countdown messages are reasons to check carefully, not reasons to skip a comparison. Make a short list before a sale; if an item is not on it, step away long enough to decide whether you need it. India's Department of Consumer Affairs guidelines on dark patterns describe manipulative online design practices.
Check the seller and exit terms
On a marketplace, identify the actual seller, its return window, warranty and delivery promise. Search for recent complaints and read detailed low-rated reviews, while remembering that ratings can be misleading. Keep a copy of the final order terms and receipt. If a price is implausibly low or the seller's identity is unclear, use a seller you can verify.
The 60-second checkout checklist
- Is this the exact model, size, condition and warranty I want?
- What was its recent price, and what do comparable sellers charge now?
- What is the total payable amount, including required fees and delivery?
- Do I meet every voucher or bank-offer condition?
- Can I identify the seller and understand returns before paying?
