Choose what you need before you look at what is on sale. Then check the seller, the exact product, and the full cost.
A discount can be useful. It can also turn a perfectly ordinary afternoon into an expensive scavenger hunt. Give yourself a few rules before you start opening tabs.

Make your list before the sale makes it for you
Write down the item, the features you actually need, and your maximum total spend. Keep a separate “maybe later” list. A promotion can change the price; it does not have to change the plan.
Compare the same thing
Match the model number, size, condition, and accessories across stores. Add shipping and fees before comparing totals. A refurbished device and a new one are different offers, even when the pictures look identical.
Give an unfamiliar seller a separate check
Search the store name and website address with “complaint” or “scam.” Read more than one source. A polished website and a padlock symbol alone do not establish that a seller is trustworthy.
Read the exit route
Check delivery estimates, the return window, return shipping, and restocking fees. Save the listing and order confirmation. Sale items can have different return conditions.
Be willing to leave
If you cannot verify the seller or understand the payment terms, skip the purchase. Treat a request to pay an unfamiliar seller only by gift card, wire transfer, or cryptocurrency as a reason to stop.
Before paying, close the product page and explain the purchase in one sentence: “I need this because…” If the answer is just “the discount,” return to your list.
