Costco is not a discount store. Their prices are, ounce for ounce, identical to my local grocery store. The only reason to go out of your way to shop at a Costco warehouse is if you have a lot of kids who eat a lot of food. But check their prices. Even though you are buying larger scale, you are not paying less for buying bigger.
And if you end up throwing away half of that gallon jar of mayonaisse you bought at Costco because it spoiled before you used it all, then you are actually losing money.
I don't know G5000...I usually agree with you on a lot and even the stuff I don't you source it and give reasonable explanations to back it. I think Costco might be cheaper, not by a WHOLE lot but cheaper
Source it? Use your own eyes! Do you not compare prices when you shop? I do. And Costco's grocery prices are nearly identical to my local grocery store's prices when you do a little simple algebra and figure out what you are paying per ounce, pound, pint, or whatever.
And when you factor in your annual $50 membership fee, plus the gas and travel time to get to Costco, you are losing money on the deal.
Seriously. Bring a calculator with you next time and do the math.
