Steam's sale calendar is legendary. Summer Sale, Winter Sale, Autumn Sale, Lunar New Year Sale, and about 40 smaller ones throughout the year. Games routinely go 70–90% off. Combine that with a Steam gift card bought at a fair rate, and you can get triple-A games for the price of a coffee.
The gift card math
Buy a $50 Steam card. Wait for a Steam sale (never long). Buy a game marked down 80%. You just paid $10 (via your $50 card) for a $50 game. Repeat.
The people who never seem to pay full price aren't cheap — they're patient.
Region matters more here than anywhere else
Steam accounts are region-locked. A US Steam card only works on a US-region Steam account. If you're buying for a Nigerian account, buy a Nigerian region card. This is where a lot of first-time buyers lose money — they buy US cards for accounts they can't redeem on.
The wishlist strategy
Steam lets you add any game to a wishlist. You'll get an email when any wishlisted game goes on sale. Combine this with a topped-up gift card balance and you're always ready to strike when the deal hits.
Bundles and gifts
Steam gift cards also work for gifting games. If your friend is going through a rough time and needs distraction, buying them a specific game they've been eyeing is one of the more thoughtful small gifts you can send.
