After placing my order, I went on a bus trip to the middle of an industrial estate to find our local sorting office so I could collect something they tried to deliver yesterday morning while I was out. Never again - the nearest bus stop is a long way from the sorting office. We even had to transfer buses en route as ours was breaking down! I only did it so the PO didn't deliver makeup while my parents are here tomorrow, and I didn't want to have to wait until Saturday to have it delivered.
Anyway, having just got home, I've checked my TopCashBack and am pleased to say that it has tracked correctly. I just hope it pays out correctly as well - fingers crossed. I'm glad to see you ladies remembered to go via TCB as well.
