Spotted these at my local Homebase nr St Albans - the one in St Albans Road ie NOT the one next to Sainsburys.
Judging by the fact that the price ticket was handwritten I think that this may only be a local deal so if anyone sees them elsewhere please post details.
6 x 70L boxes for less than a fiver each seems like a bargain to me.
Seem to be reasonable quality but I only bought them today so can't really comment.
Note that the base has roller wheels so I don't know whether they would be a help or a hindrance. I've never bought boxes with wheels before but these seemed too good to pass up wheels or not.
Thanks to HIRALV for posting the link - the SKU number appears to be
373983 if that helps anyone.
