Stop us (Exploit, PHP)

You cannot stop us!
Noother has created a business to sell .xyz domains for some bucks.
Your job is to find a hole in the script that would allow purchases without paying for it.
You can test the script here.
To help you in debugging, you can take a look at the sourcecode, also as highlighted version.
There is a second file involved for the purchase table: noothtable.php, also as hightlighted version, but you probably don't need it.

Good luck!

Thanks go out to jjk and dloser for testing the challenge.
