Happy Birthday Need, I hope you have a lovely evening 
A microwave is 700-1000w, so running it is 7-10p an hour on my tarrif. But it's not heating all the time. If you ran it 10 minutes it would be about 2p.
You can do jackets in a slow cooker.
A cheap halogen oven would save money, they're very good for small families. It's 1200w heating 12l of oven, even my tiny built in oven is 2000w heating 53l of space. It heats up instantly.
£3 Tesco, cheesecake and cat food.
Totally fucked up dinner, Dh has had mash, gravy and yorkie puds. The beef went in the sc too late. I've had half a cheesecake.
Shoes going back, too big & slightly damaged
