You must bring your own cart - because if you were truly filling it with those grocery items you would barely cover the bottom of a Costco cart for $150.

Just picking up chicken, pork, and fish (we get our beef from the ranch) we are easily pushing $150 and that is only 4 or 5 packs of meat.

Most of our cart is groceries, cleaning supplies and other household consumables.  Rarely walk out for under $300 - most of the time it is $500+.  Shopping about every 3 or 4 weeks
