Seriously, what the hell kind of cheap sticker are they using.

Take heart, though, as there is an easy solution! There's this wonderful stuff known as Ronsonol, it's lighter fluid that comes in a yellow and blue plastic container that's available from most drugstores. Unlike most lighterfluids, Ronsonol is naphtha based and incredibly effective at removing almost any stick (worked in a used bookstore for a few years and we used it for getting stickers off old books—very effective). It wont stain and it evaporates very quickly!

Just be sure to buy Ronson, as almost all other lighter fluids are nasty butane-based stuff that wont get rid of stick and will just leave you with a big stinky firehazard (though they are actually better lighter fluids).
