They were Nassau Golf overruns that Costco bought up and rebranded. More than likely just like the Taylor Made LP Red for a few years ago.....probably a loss leader just to get people into Costco.....Titleist is breathing easy now....
Something tells me Costco won't let this die -- they smell margin. If they can sell 100k more memberships by buying Nikes capacity (or convincing Snell or Vice to sell them some) and taking their normal slim margin that's ~$10m? Worth a couple calls.
I think the problem is that there aren't very big margins in the golf ball business in the first place, and Costco will have a hard time duplicating the price that they were selling these balls for as a regular production instead of an overrun like this apparently was. I don't know if any of you remember the Kirkland golf gloves a few years back; they were as good as any golf glove I ever had, and they were selling for about $6 a glove. They are long gone, too, and I don't look for them to come back, either.
The selling point of the Kirkland brand is usually more about quality than low price anyway, and at that, you have to buy in bulk. This price of $30 for two dozen was a complete anomaly; I don't look for it happening again anytime soon.
