Things have been so hectic the past several weeks that I didn't get a chance to purchase a Costco club membership in order to be able to order the balls and try them out.
Judging by the reports of them not being available for longer than a few hours after they restock inventory, I'm kinda glad I didn't sign up. Maybe when the hype and interest dies down I'll reconsider. But I'm not gonna spend the money on a membership just to realize I can't get them at the moment.
I'm sure they're a great value based on all the reviews, but it's not worth the added hassle given the fact that they can't keep enough on hand to satisfy demand. I guess I'm just not that patient.
