Hey GC! I'm trying to order a bong off the shop and use a discount code for 30% off and it's not working. The reason i'm concerned is, it was going through a few days ago but my credit card wasn't working so I had to wait; and now it says invalid code?! I need that 30% to order because atm I'm limited to $100 or I can't So can an Admin please help?? Also here's the bong I'm trying to order http://www.grasscity.com/us_en/straight-cylinder-9mm-glass-ice-tube-40cm.html#.UfFmjG0o6Uk Thanks so much if anyone can help or knows what to do.
