Forum:Fallout New Vagas general store

When I go to the general store in Fallout New Vegas and talk to Chet, I can put things in my "cart", but can't buy them. It will only let me exit. How do I buy weapons?…………

You have to hit the X button (on the XBox 360, not sure what the buttons are on the PS3 or PC) to finish the transaction. Hitting A or any other button won't do anything. Basically buying and selling is like a "trade" in these games, since you can do both at the same time and the game calculates how many caps are changing hands.
