One thing to note, if you list a $1 chip in an auction format at $2.50 with free shipping, your profit is -92c and -$1 as a buy it now!! Ouch!
You would have to sell a chip(if you dont charge buyer for shipping)for $4.68 to break even on a $1 chip and $4.85 in a buy it now format!(assuming you paid a $1 for it ) Sooo, to make a $1 profit on a $1 chip that you paid a $1 for, you would have to sell it for $5.81 or $6.02 in BIN format! Doesnt pay to sell $ chips on ebay!
