I am panicking as was given £100 tesco gift cards by MIL with instructions not to spend until after Christmas (they were my Christmas present). But I have used them today as we are so strapped, I used them to buy groceries and washing powder etc as we are struggling so much. Is there any way she can find out? Will she get a notification to say the gift cards have been used? I'm really panicking as I don't want to upset her and I'm worried she will get a notification which shows I've spent them before Christmas. Anyone know how tesco gift works and if they're tracable etc? Thanks v much!
