Release If you were the supplier to Kirkland Signature brand and the test market batches sold out within days , wouldn't you believe that you could negotiate a little tougher before agreeing to a long term deal ?
Again, I don't think Costco would bite. They know why they are selling out in minutes, and they also know if the price goes up(by very much), eventually, they will sit longer on the storeroom shelves.
I know if it was my biz, I'd say sorry, but NO deal. Prices go up, demand will always go down. At least for my wallet.
Wonder if Costco has a written deal on these balls, as far as patent or whatever. I ask this knowing that they got no idea about the ball's manufacture, as they defer any questions to the factory. I could see another company stepping in and taking these balls away from them, if there is no blood deal.
