First of all, why can't I buy with my money in the bank? I think it's faster since I don't need to withdraw my money first and then go to the store and buy stuff. The former will allow me to buy just like buying witht a credit card or check (which is tied to my bank account).

Second, where can I find the price of each merchandise in the store? If I want to buy something, I wanna know how much is it first and if I have enough money.

Both are kinda lousy design if you ask me!!!
