Don't expect Shou to work with you on price at all. He says "make an offer" and if he doesn't like your offer, rather than counteroffer, he'll send a rude reply and then just ignore you.
Apologies if you think it was rude but your offer was by far the lowest out of several forums and PMs. Not to lump you in the same pack but I am tired of people saying I'll give $50 for all of those games which is obviously not even close to market value. If I offered $100 for a mint complete Sapphire, I would expect to be laughed at, if I got it for that much, great, if not, I wouldn't complain about it as I'm trying to get a really good deal.
In these financially trying times, there is a reason why people are selling games with high value. If you don't agree with the current value, you can always wait for someone else who doesn't need the money or value a given game as much.
Also, apologies to the original poster, didn't intend to hijack your thread.
