is there a phone number i can call? i want to know when they issue vouchers for nvidia cards. i don't want to drive each day just to find out when they get stock

They don't have a phone number, you have to do everything online or in person.

All I found was an online info exchange for troubleshooting.

If it is that important to you, ask one of associates for their card and\or number. Doing so may even remind you to ask for the store number and proper department extension.

Website only info.
