It's getting to a point where I dare not add anything to my 'watch' list... As it now seems to be impossible to delete anything from the list!!! This wasn't a problem before, only recently I haven't been able to remove anything from the list !!! Anyb...
The current offer from Nectar is for 6x points and 250 bonus points. Is that for a single transaction/purchase, or can it be for a number of transactions from different sellers? xx
