Sure, it's good for the seller, but not if you want to buy the game as cheap as possible. Besides, if you have bad luck, you pay more money than if you had bought the game at an on-line shop.
edit:Ah, now I understand! A "For Sale" subforum where the users of this forum can sell their games! (But who would actually sell these good ol' games if that person hasn't a 2nd original copy of the game or desperately needs money
I don't think you understand how e.g. eBay works, you NEVER pay too much, that's the MAXIMUM AMOUNT for.
Let's see you find Loom FM-Towns version originally wrapped, new and NEVER used
(hehe, the "Holy Grail" - hey, Indy around???)
You see the price starts at 1$. You don't know how much this pearl will climb, but that's completely equal because YOU know what you want to pay at a MAX for this piece. So you type in your MAX, or wait and try in three or four steps, say your MAX will be 100$, which would be ridiculous until you are VERY lucky, because this game can climb to 500$ or more nowadays on eBay, even used or in bad shape, even without package
eBay will END bidding when your MAX is reached and you will loose NOTHING except the game, but still you didn't want to pay more than 100$.
So why do you pay too much?
OTOH i would NEVER bid on an article i can still get from a dealer, too much risk, sorry
Such an article on eBay will draw the fans and collectors sooner or later especially when you make enough noise on fan forums and the price will rise simultanesly the number of potential buyers will. I know this is again from the sellers POV, but seriously do you still believe eBay is for Buyers?
