Body shop has quite a few 2 for £10, 3 for £5 offers etc but if you put just one of the items in your basket it seems to take the money off.
For example, lip butter £5 each, 2 for £8 but having one in the basket takes the price of it down to £4.
Seems to work for all products in an offer. Not much of a discount but every little helps.
Couldn't see this mentioned before so sorry if it has been.
Also 18% quidco and lots of vouchers around.
