I utilize the “babe I just sold X So I’m going to buy x” approach. 20+ saddles and various other hunting gear bought and resold this way so it’s worked well for me.
My wife Is a saver and a penny pincher so even if buy and resell she thinks I spend too much money. She’s doing better at getting over it lately.
I'm a shame to say I use my kids as reason why I have multiple of the same stuff. "But honey if the kids get interested, I need multiple sets!"
