It's the dishwasher tablets. I've been hanging out for 10p per tablet. I've not been able to get that price. I ended up getting some extremely inexpensive damaged tablets that were extremely inexpensive. They are okay, but they are leaving a residue, and some fail to clean. It's a false economy. I'm going to have to give up and buy some proper ones - at 20p at time!
I've given in and bought a very cheap duvet. It was £9. The other one has started to shed tufts and I don't want to inhale them in my sleep. I don't expect the £9 one to last much longer.
But every now and again I get a bargain. Today I got three rolls of Christmas wrapping paper, extra wide and 3m long at 50p each.
And while typing this I managed to find a good deal on Asda for dishwasher tablets, so they will be down to @ 11p each. So things could be worse.
