Tried to use my D.C. to buy some Coles MCGC today (no longer have an Amex Edge & wanted SPG points at max earn).
Declined. Spent 40 mins on the phone at self checkout with constant reassurances from D.C. We're going to resolve it at any moment.
They also asked why I was buying GCs with the obvious answer being D.C. acceptance is minimal so this would help. After they started asking specifically what I intended to pay, how much and could I substantiate it, I told them to forget it and I would be paying by Amex. I think wth GC strategy is a legitimate, if not time intensive for those of us committed to point collecting, way of legitimately earning points with our favored payment method at places where it's not accepted.
However, with the increasing compliance focus, we run the risk of being seen as money launderers and then to spend valuable time proving we're legitimate. D.C. wouldn't approve the $525 charge initially and could otherwise only approve the lot (10 x $525) in one line.
Ended up using my Amex Explorer with slightly lower earn rate.
Bit of a rant. Disappointed with D.C. as Coles is one place you can reliably use it. Not much point in having it otherwise.
