Don't discount it to £0.01, that is just stupid. The obvious scam here is to take high value items and mark them down dramatically. For example, marking a £200 phone down to £20.

Not that I approve of this...

The less obvious and more ethical thing to do is to buy two identical products, one for 10p more and one for 10p less.

Wouldn't it be more ethical to just scan the item without buying it?
