I have had a Sam's Club membership for the past several years and shop there regularly. Recently a Costco was built in my area though and I'm considering getting a membership there instead. I've heard so many good things about the store, but I've never been in one. Does anyone know enough about the two of them to compare? From what I understand, Costco is more expensive but healthier. I got my membership at Sam's initially to save both money and time shopping. Money is not as tight now though, and I am trying to get my family to eat heathier, so I'm thinking Costco might be a better fit.
