I'm pretty sure you'll never see me in a Costco - at least not to shop. The very idea of having to buy a limited selection of goods in the form of a pallet or bucket in exchange for a membership fee in order to "save" makes me want to grab the shopping bag to buy fresh food at the nearest market in the exact quantity needed to supplement those in my anti-food waste bag to make a quality meal. Who wants to chew on a pallet of pizza for weeks just because it was cheap?
LOL
Many goods are displayed on pellets, to save on shelf stacking labor. You don't have to take the whole pellet. Single pizza's are available Below is $15.99 (1.1kg)
Also the stuff is not cheap two 640g pams pizza's at $3.38 each from pack n save would be a much cheaper option. But based on the slice I had from the food court, costco pizza seems quite good.
There were a lot of things that I looked at, and thought it looked good, but the quality it was offered in didn't even close to remotely work for my household (normally 3 people, but will be 2 people for the next week).
Costco will not replace a weekly supermarket shop for most households (unless your household has enough pantry space to store sugar you buy in 25kg bags). Based on what I see today, most shoppers are picking up non perishables, and stuff like giant packs of chicken or mince to repack and freeze.
For costco to work, the household needs to be both time rich and have reasonable financial resources. Took me cira 4 hours to do the costco trip today incl travel time. And for it to work, the household needs to be able to afford to buy several weeks of say toilet paper in one transaction (and have space to store said toilet paper).
