Just picked up 4 of these at a bargain price of only 75p per tub.
These are usually priced at £6.50, and are occasionally £3.25.
These are the pink tubs, which are for colours and darks.
** EDIT** The white tubs are now 75p as well (seen on 29th June)
May be specific to my local store (Leicester Fosse Park).
But worth checking your local at this silly price.
