Went into Woolworths yesterday to buy a toaster. I saw a matching set somewhere else so I took the toaster back to Woolies.
It was £30 so with 20% off I got it for £24.
I took it back with the receipt and the woman on the till refunded £30 instead of £24. So we made a £6 profit. I didnt notice until I got home as I would have mentioned it to her in the store as £6 is nothing in the whole scheme of things.
I hope this doesnt prompt everyone to go out and try it but I thought I would highlight someones stupidity.
