Look at the Royal Mail Website, there is a Fraud Report section.
If it is for anything like I give below I would have thought RM would Monitor sales on here.
I have seen those selling used stamps, not long ago there were people sentenced for washing/cleaning post marks of stamps and reselling. It involved very large sums of money
I see that the seller states not for re-use but what other purpose are they for. I have reorted to ebay but as usual no action.
