Cheating Amazon book shops

I just had a look at who has 'used' copies of Manna-X - no one should be selling any because I know EXACTLY who has a paperback - not many and it's not any of them...
So, let's look at the list and prices of all these CHEATS...so there's a shop which has a used Manna-X for $999.11+ $3.99shipping? That's over $1000 !!!! And if they do sell that one copy (which they don't have because they didn't buy it) I would see $2 of that - perhaps...
