True that everytime I shop there the quality/price ratio is the highest you can find. They do not sell the very cheap stuff like WallMart. The problem is that the specific Costco in Oxnard is way too packed, if you can go in non-rush hours it is OK, otherwise there are long long waiting lines for the registers all the times. Interestingly, their pizza is better that pizza hut, domino, pappa John etc. But again, there will be a long waiting line for the pizza too.
We have saved a lot of money with costco gas. I am so glad they have a pump station in Oxnard, because not all costco warehouse have them. Also the merchandise they carry in Costco are always of the best quality. I havent been disappointed with them even once in the 6 years I have been shopping with them
