Boots have variaties of centrum 30 tablets Centrum multivitamins on offer for half price, they also have the 3 for 2 offer still going on. So you can buy 3 Centrum boxes for the price of one. If you don't want to use the 3 for 2 you can just buy them for half price starting from £2.40
I just bought 6 and paid 4 instore.
