| Re: 130 Dunes chips
You definitely don't have to list how many you have. A lot of eBayers will sell the same item(s) over and over, without any indication of when their supply will run out, etc. I see no problem with trying to maximize your profits.
To absolutely max out, you would sell them one-by-one, listing only one at a time. However, if you really have 130, this will take a year or two... CTers will generally pay a fair fixed "price per chip" for any volume, but you're definitely not going to get $45 each! (even on eBay, you'll average much less than that). I'm guessing you're not in a huge hurry (especially considering they've been sitting in your closet for quite some time). If I were you, I'd probably consider selling them in lots of 10-20 on eBay. But you might get several offers here before you even get that far... |
