If I reedem them, can I buy myself a VPS or something?
Please don't get this wrong but I cannot sell you since you have negative feedback. Only couple code left so escrow always welcomed.
i asked a question. I didn't say I want to buy
Oh, yes. You can open virtual servers, send mail, build internet of things product, content delivery network and etc...
I personally use for a physical product and for my website, so far speed and connection is good and hourly prices are cheap.
