I shag these balls at the golf course. $25 gets you a shoebox full of 100 of them. There are many different kinds, including a lot that are like new and very expensive when bought at the store: Titleist, Callaway, Top Flite, etc.
The box pictured is what I have left. The balls are several different colors.
The balls are sold as is. Some are like new, a few are scuffed, and a few have marks on them from the golfer. But you'll definitely get some good ones for regular play as well as some for the driving range.
I live in Ellensburg, but I travel sometimes so I may be able to deliver them to you.
