Possibly, but in my opinion probably not. Costco is selling these chickens for $4.99 each. It's a loss leader, and (as far as I have heard) Costco is adamant that this price will not change. I think Costco is simply trying to reduce the amount of loss they are taking at that price.
* I know it works on me, I go in for the free samples mostly and regularly spend $50+ on a visit (maybe half the time), and just recently spent $7,000 on a massage chair.
