I have checked the Aldi Facebook page and it has just been posted about an hour ago that there will be a £5 off a £45 spend voucher in the Daily Mirror & Record this week on Thursday.
They seem to be varying the amount we have to spend - I am sure last month's was off £40 but it has been off £45 a lot of the time.
I don't think I will be taking up the offer this month, as we are pretty well stocked up, and I have a Tesco delivery coming in the morning. When they offer you £15 off a £60 shop [which amounts to a 25% discount, surely] I don't mind spending £1 to have it delivered. The diesel to go to the store would cost me more than that!
I do hope that the Aldi voucher info is of use to some people - I'll be looking out for it next month, I'm sure.
