Crocs-no "'mystery"' gift-Ngwenya ate my cash

I visited East Rand Mall Crocs, liked the refreshed products on offer, and bought two items.

The issue is (the cash till doesnt display items, and the receipt gets emailed to self, so not discovered till later)

The "mystery gift", choose? got a pair of socks, except one gets billed for this "gift"", r100 (retail speak, r99.95!)

Beware the hungry crocs!
