It just sells. She lists on lots of reseller platforms. But the algo rewards daily consistent activity. She hacked it so by listing 3 new items a day, after building a 200 item base, that she sells like 10 day when she edits 18 other items that the system treats as new. So basically, bulk daily activity of quality used items well photographed at prices retail feels is valuable even though she is making a 10 dollars out of 15 cents.
