DM is pretty much housebound, I have done her shopping every week for last 4 years and it is becoming a big bone of contention. I have no income, but have to pay upfront for all her groceries and other stuff and try to squeeze a cheque out of her every few weeks to pay me back. But it's so hard to keep track of the supermarket bills/ toiletries from Boots/ occasional online orders/ wine orders/ birthday presents I have to buy for her to give to my dc...so I'm often out of pocket for a bit and get overdrawn. It's really bugging me. Especially when she rings up unexpectedly sometimes asking for a pile of cash. She thinks it's OK to do this as she'll write me a cheque when I take it to her, but a week can easily pass between withdrawal and credit.
I'm so worried about looking like I'm trying to fleece her that I don't really want her to set up a standing order to me, and the costs do vary a fair bit from month to month. So I've been wondering about suggesting that I have her debit card (she can't use it) and PIN so I can pay directly for her stuff from her account.
But I cringe even writing this - it sounds so dodgy! Is it illegal? Or just immoral?! What else could I do? Would it be any less dodgy to set up online access to her account and just zap money out to my account as I need it?
