Convince stores are a different animal, I worked at one briefly have seen the invoices, the merchandise that comes in the door is almost always at a higher cost than Walmart retail, but they beat Walmart pricewise on things like milk and cigs.
It's a well established American thing ( the conveince store ), where people will pay $2 for one roll of toilet paper instead of buying 20 rolls for $9 at a real store.
Many owned by people from India and family operated, it's a great business with many ways to cheat and profit...and I know what they are !
People will pay virtually everyany price for a can of catfood or some stupid shit instead of buying a case of it at the grocery store. They are
already there for gas and cigs and will buy other shit where the price is much higher out of necessity.
I stockpile non-perishable items like toilet and towel paper when on sale.
I used to work with this lady that had the philosophy of , I don't need it, but I can't afford to not buy it at that price ! I would have pursued her but she lives in a double wide trailer and has like 8 cats, I like cats well enough
but not every fucking where
When my last cat died, I buried her, and was also happy to get rid of the litter box, no more animals for me !
A cat can live 20 years, I probably don't have 20 years left ? I don't want the cat to starve to death if I drop dead and my body is found weeks later
As far as stockpiling things on sale...you have to have room to store all that stuff. Takes up a lot of cupboard space that a lot of people dont have. I think it makes a lot of sense for larger families though especially if you have a storage room or walk in pantry.
There is something to be said for minimalism too. Only buy what you will use in the next couple months
