I guess customer service is a lot like car or home insurance, you pay a lot of money and don't know if it is good or bad until you need it. I'm both a Costco and a Sam's member but have never had any issues with the product that required refunds. I prefer Costco meat by a good margin. However, Costco pisses me off on a regular basis by carrying something really good and discontinuing it for no apparent reason. Next year, when we retire, I'm thinking that I should pick one. Maybe the opposite of what my neighbor has and we can trade off for each other.
