This is the first time I hear someone claim leftover balance vanishes from Steam Wallet. I am unable to find anything confirming this, and it goes directly against my direct experience, because I have had some leftover balance in my Steam Wallet for years now and it certainly never vanished. Can you link a reliable source for your claim?To each their own i guess, i wonder wehat happens to the left over balance of wallet funds? Oh yeah it vanishes after a year. I have been wondering just how i could add
to my account? Or how do i add $10.30 to my wallet? Yes thats right you can't but nope no trickery there at all.
Also, no, if you want to randomly add 10.98 (USD, EUR, whatever) to your Wallet while not actually buying anything, you can't, you can only do certain increments, that much is true. However, if you're buying something using Steam Wallet, then with any sum above the minimum 5€ (not sure if it's the same amount in dollars), you always have the option to just add the exact amount you need to cover the purchase. So if you have nothing in your Wallet and get a 3€ item, you do have to add at least 5€ (and you will have 2€ left in the Wallet for next purchases). If you are however getting say a 6.50€ item, then apart from the option to add 5€ or 10€ to the Wallet, you also have the option of adding exactly 6.50€ to cover your purchase, or whatever is the difference between your current Wallet balance and the price of the item you're buying.
So, yeah, really don't see where the trickery and such comes from. But I mean, you're obviously free to ramble about trickery all you want, that's your prerogative.
