I have just bought and used a half price Dirt Devil vacuum cleaner (40.00) from Sainsbury's. It was supposed to be an upstairs vacuum but it's so powerful, it's staying downstairs and the older on is moving upstairs.
I didn't intend to buy it today, just went food shopping as usual and it sort of jumped into my trolley. There were lots of half price goods on sale but there was no mad, stupid rush to grab things off shelves. I am pleased with myself as I've been intending to buy an upstairs vacuum for ages. Hurrah for Black Friday! Actually, its Black 'end of November' sale for Sainsbury's and many other shops.
