Went into Tesco Loughborough on Monday and saw they had clear plastic shoe boxes like this: http://www.aplaceforeverything.co.uk/shop/index.php?page=201
for £2.50 which I thought was a pretty good buy anyway.
Got to the checkout and it scanned at 62p! I couldn't believe it!
Even if you don't want to put shoes in them, they would be brilliant storage boxes for other things, they have a good clip on lid.
Definitely in-store, not sure about online. They were in the first aisle where Tesco have their "seasonal" products (i.e. where they have all the Fathers Day things, cheap DIY items when they do them etc).
I will try and attach a scanned in image of my receipt:[email protected]
