Really Useful box 64 Litres £4.36 instore Homebase
Went to pick up one of these this morning as cheapest local price and was expecting to pay £14 for one.
Anyway my local store had them marked up at £4.36 which I didn't quite believe so took one to till to scan thinking it was a misprice. Scanned at that so went and picked up 4 more lol!
They had about 10 left after I took my 5 in my local store. Didn't think there was much margin in to sell on eBay...
No doubt store specific but worth a look.
