budget: above $0 Sell Me Your Unwanted, Expiring .coms

What is the meaning of
$0.25
$0.50
$1.00

25, 50 cent

$1

Thanks.

Bought about 300 domains so far and still looking for more. (10 domains minimum per transaction!)

Im sorry I don't understand. Why would someone sell a domain for .25?

This is for unwanted domains the owner was going to let expire. It's much better to get $0.25-$1 per domain than nothing at all.
