It’s just price gouging. There is an item I sometimes buy that is about $1.60 at supermarkets, but is consistently $.85 at nearly all rural Colmados. Same brand, same product , shelf stable , mass produced, large volume mover, imported product. Supermarkets have just collectively decided to sell it for 2x the “rational” market price because it went up with Covid and people kept buying it.

Colmados don’t do data driven pricing, and just do a flat markup on the stuff the suplicadoras bring them.

Data driven pricing is just selective price gouging under a different name.
