I seem to remember this happening once before in the past. The fly shops tossed a fit (rightfully so). If I remember correctly, Sage sold the rods to a company that were supposed to retail them in a different venue. The third party sold them to Costco instead of the outlet they claimed they would use. I don't know if that is the case this time but I know Ford dealerships would certainly take offense if Costco started selling F150s below dealer cost. Fly shops rely on exclusive rights when it comes to selling high priced flyfishing gear. If those products show up at Costco at ridiculously low prices, this does a lot of damage to the fly shops. In this day and age, fly shops have a hard enough time keeping their doors open due to competition from web sites and big box stores. The last thing they need is competition from Costco. This is a very bad deal for fly shops.
