LOL!
Actually a better remedy is to hide them. Grab one copy and stash it spine-out in the cooking section, another in the gardening section and so on. Then when someone comes in looking for it, the retailer will punch it up on his computer and see that he has 8 copies available but can't seem to find any of them. Thus the book doesn't get sold and it is unlikely he will order more copies. Do this in the library as well.
The liberals have been doing this to conservative titles forever --especially in college libraries. It is dirty but effective. We need to play just as dirty.
Stay safe !
