As a seller from time to time on oldgas I have had decent results with priced items and auction style sales. However, what does it matter if an item is priced? If you want it you'll ask. You're cutting off your nose to spite your face if don't ask about an item you really want just because it is not priced in plain view. I personally like a priced item because everyone gets the same price. Not always the case when you have to inquire. But that really doesn't matter. To mandate a price be shown is more regulation that's not needed. Price it or not, those that want it will call or email. Leave things the way they are. Remember to send a small piece of sales to oldgas from time to time for the opportunity to sell to an interested audience (not required, just the right thing to do)
