I find it sad that there are people who think because someone makes a mistake you should be allowed, in fact a 'right', to take advantage of them.
I understand if you don't realise and their mistake sets you back you should get some sort of resolution.
But come off it, everyone in these groups knows when it's a pricing error.
These groups are fun, I do like them, but when some members think they are entitled to something because mistakes happen I have issue.
