Sales at:

20

26

Originally excluded 26 due to an aged seller at 22. However, the seller has since sold (refer to #6), and given the owner is a 3rd party site’s bot that requires you to visit their site or add them, it would be best to not take the seller into much consideration.

Going with 20-26.
