I complained to a company the other day that I was not satisified with a product of theirs. They sent me some vouchers in the post so I could go and buy the product for free again.

I just popped to the shops and used the coupon and realised that I can use 1 coupon several times at self checkout without any problems. I was just wondering how traceable this is and what are the implications of doing such a thing?

The voucher popped up as a "Supplier Code" on self checkout and on the T&C's on the back it says it is limited to their own products, I have not tested if it can be used on anything else yet.
