No yarn shop like the ones in Colorado. Most yarn boutiques in CO let you use their yarn winder for your yarn at no cost. This location charges you per oz. to wind your yarn (bought out of state).
Because of that I would prefer to order my yarn and have it mailed to me...and buy another yarn winder.
Let customers wind their yarn for free and gain new customers or don't allow it and don't gain new customers.
As for me, I'll shop elsewhere.
