In the run-up to Xmas, if I spent more than £60 on a Waitrose shop three times in, I think, a month, I got sent a voucher for £30. Not difficult to spend more than £60, if you're stocking up on wine, Xmas chocs, biscuits etc. Or even stockpiling washing powder or whatever. And £30 is a v nice bonus.
Whereas with Sparks, if I buy a fruit pie in the next 11 days I can have 20% off. Whoopdedoo. They've just been on offer anyway. And I had to change my password to reregister, because it wouldn't accept the original one. I'm annoyed people are getting chocolate because I do buy their hazelnut Swiss bars.
I mentioned to an assistant that I had a Sparks card but hadn't quite got the hang of it and she said, 'You and however many million others.'
I used to use my M&S card as my default credit card for the reward vouchers, but I'm changing to my John Lewis one now.
