Been wanting one for ages and so just order a coin sorter (half price at £9.50), using code 4000 for £10.00 off and free delivery, as posted previously on here. Then tried code 1191 for a free 6 piece towel set, comes up as £0.00! Couldn't find anything for 50p...
Seems to have worked!
I dont think it works anymore but was great while it lasted!
