I suspect they are supposed to be £5.50 each and you picked up the entire display case.

Good blag though! And their loss!!
:-D

Now I come to think of it I think this box was on the shelf for single filters!

Yep it has happened....

How did you do it at the till and the cashier didn't realise it or Self scan and yo used one to scan for all!!!

Please take this post off now it is not a deal that is going to make me get out of the house now!!!

Reminds me of the time I bought a small umbrella from Argos. They gave me a large box which I questioned and they then realised they had handed over a box of 30. I was happy to have just the one.

Not surprised you paid a fiver as the receipt shows price for a single cartridge. but grabbing a whole box of it- its another story. You should take it back.

OMG LOL

good for you op

Otherwise known as shoplifting.
