Our regular listings are approximately 4300 but we list about 40 one off listings a week but have to use a third party less reliable software for the eBay copy to Amazon many times missing our inventory balance.
Do you know that if you have a UPC number and create an item on amazon that they will accept that and give you the ASIN number automatically. I wish that sixbits would look at that very simple process to allow us to put in UPCs then send to Amazon and bring back ASIN in next interface.
UPC numbers can be purchased for a little as $0.22 each for 1000
