Yep my daughter went and got us one each, they are only at Tesco and are about 4 pound each think it's a really good idea for kids. We got my son a small grooming one from Superdrug and hubby is getting a tea one. Dd got the Rituals 50.00 one last year and it was filled with lovely things, she got me it for my birthday and she got the deluxe one.
There's a Swizzels sweets (drumsticks, refreshers, love hearts etc...) calendar for £4 in Tesco. B and M do a larger Swizzels advent cottage for about £12. B and M also sell a Haribo one, Yankee candle one, Millions (the little chewy sweets), and Pringles (only 12 days). John Lewis do a few Lego calendars for about £15 each, a Premier League card one, a tea light one (£25), stationery (£28), gingerbread (15), jelly beans (£15), green tea (15), several phenomenally priced beauty ones and some very pretty wooden ones. Take your pick! Apparently Asda is going to sell a cheese one for under £10.
I saw two diff beauty products one in Superdrug. The biggest one was a full sized product a day £75, and a smaller one which was smaple sizes I think - can't remember the price. Was too wow'd by the big one (didn't buy).
DDs have a Christmas Letter advent calendar from here. It's fab.
