Provide what customer's want
If you pay attention to what's selling, not just the revenue, you can boost sales very quickly. Just lately, it's been Australian KGV heads, with or without varieties, which are selling like hotcakes for me, with three new regular customers having "found" me. Customer's are getting very fussy about the back side of the stamp, insisting on MUH over MH, but used are selling as well. These are a few I've sold this week, and I think I know what I'm scanning this weekend 😊
