if im in the PH, can I get the code of a US steam wallet?

and use the money to buy something here in toribash WHILE IM IN THE PHILIPPINES?

There are alot of sites where you can buy usd walet codes while you're not from the US, like this: https://www.seagm.com/steam-wallet-card-code-sea
But I guess steam would convert it back to your currency as said here: https://support.steampowered.com/kb_...0478#different

But I think you can just buy things from the torishop with about any currency, even tho it says the amount in usd, when I try to buy something of 5usd it just says it costs €4,20

thanks, ill try
