Now, about adding custom amounts to your Steam Wallet... Unfortunately, you can't just add any random amount you want - Steam has some rules in place. You can only add predetermined amounts, like $5, $10, or $20, using the Steam website or the Steam Client.
But, here's a quirky fact: did you know that you can use Steam gift cards to add custom amounts to your wallet? It's true! You can buy a gift card with a specific amount, like $25 or $50, and redeem it on your Steam account. It's like a little workaround to get the amount you want.
Another fun thing to note is that Steam sometimes offers sales and discounts on games, and having a custom amount in your wallet can be super helpful in snagging those deals. You can even use your Steam Wallet to buy in-game items or subscriptions - it's like having your own little gaming economy!
