Looking to get a few really useful boxes to place some of out stuff in storage, these are tough and easy to stack.
Searching around they seem to be £15 plus.
Managed to find Robert Dyas selling them on a '3 for 2' offer. which makes them cheap, but just noticed a 15% discount code DYAS15 which makes them even cheaper.
Just grabbed 6 for £54.37
Sneak in 1% quidco also gets them for around £9 each!
Hope this helps someone
