I'll explain, when you walk into 7-11 or something, there's prepaid giftcards which are acted as credit cards. Like Visa's and mastercards. There are a specific amount of money you have to pay for what you want. you pay 50$ for a 50$ gift card, but there's more prices.
Because when I was selling accounts, to other people they most likely used these giftcards, and for some reason they keep forgetting what to buy and what the prices are. I was just thinking of reminding those people that these are the prices. Speeds up the process.
