So, someone listed a Diamond Combinator for 55,555 points. I guess they are thinking they want to end up with 50,000 points after 10% tax. What they don't realize is that they would already have 50,000 points because you cannot receive less then 50,000 points for selling a Diamond Combinator.
What makes this worse is someone is now competing with the 55,555 sell order by listing for 54,545. Um, either one of you would already have 50,000 points now if you would just list for 50,001.
This applies for all levels of Combinators...
Perfects - you will receive no LESS than 100,000
Diamonds - no less then 50,000
Gold - no less then 20,000
ETC
