Costco isn't really a place you go to every day, or even every week. Most people I know only go once a month at the most. You go to buy the big bulk items, and those last a while, weeks at a time usually.

Then you have the local grocery stores for daily and weekly things. Rotisserie chickens are at nearly every store, and from my experience they're all about the same size and price. Discounted ready to eat chickens aren't unique to Costco.
