At $2.50 a can retail, I should be able to do better online. Beverages Direct doesn’t have it, and there website just directs you to 7-11 and "other fine retailers".
I go through about 2 cases of Red Bull/Go Fast/Bing per month, so I need a good price for quantity.

This is the site i have always been told to send people to for purchases in quantity. https://www.t-nation.com/productInfo.do?id=1273809

also, you might talk to 7-11′s in your area, if they will cut you a deal on a case. i have several stores that do that regularly for people. you might not get as good a price as from that website, but, you also wont have to pay for shipping. also, if you live in colorado, i may be able to point you in the right direction.
