Buying Items While Not Signed In

Hello I had just made the mistake of buying an addon but not being signed in. This is a big problem. Gmodstore needs to make it where you MUST be signed in to buy a script immediately! I know next time I need to be more aware and careful but I shouldn't have to worry about running into this problem. I hope Gmodstore really takes this in consideration about fixing this. Thank you very much your regards bear.
