My last transaction with MCGC from GCcom was last month and it was a PITA to drain them via split tender. For whatever reasons, even when I pressed the green Debit button, the next screen came up to signature screen on the first card. I decided to load it to reloadable prepaids $500 at a time and with the cancel hack, I finally succeeded. I do not usually order MCGCs unless there are random offers that come up but with my experience, I will just stick to Visas that are quicker to drain via split tender.
