What can i do with my +$200 steam wallet?

Buy a bunch of games and gift them all.

Buy Me Rogue Warrior And I'll Give You Binding Of Isaac + DLC

DeadIsland and The Walking Dead.

try to put the games you actually want in your wishlist then start buying them :) and ofcourse we all know steam sales are on so a lot of discounts there

Buy stuff on steam sale only. $200 can go very far. Buy a couple of them and give away here or reddit.com/r/RandomActsOfGaming. There are people out there who don't qualify for this site because of a lack of games/money.

Give me a copy of The Witcher 2 :D

You can buy load's of game's with that much money, wait for flash sales, sometime's it has awsome games with good prices.

Despite what people say about "you can't transfer Steam wallet funds", I can do it for you if you give me your login details :P jk

Buy tons of "Dead Rising 2 Complete" Packs and sell them to Germans,they're after it

get some of the dev packs which have the games you want?
