Before 12/1/2017, I could order up to $2.5K twice a day up to rolling 30 days but since the portals instituted the $30K cap which probably applies to all online VGC merchants per account/address, I had trouble getting in two orders per day with GCC; at least from experience, they didn't put a hold for days/weeks on pending charges so the large amount didn't tie up my CL. GCM is notorious for holding on to pending charges for transactions they reject/cancel and we're just at their mercy and CCs are of no help either.
