$25I got "catfished" last summer, went to look at two used tires sold by a "woman." Was a dude and he had a whole yard full of them. He wanted $50, I offered $40, he refused.
Nine months later, he/she still has them and dropped the price to $40. Instead of hoarding stuff like this you've got to churn, baby, churn! Any reasonable offer should be accepted. I should go offer thirty bucks.
