I get a significant chunk of my food here in Canada from Bulk Barn - where you can go and refill your containers with what you want. Besides grains, dry fruits and spices, I also get peanut and almond butter from there. The peanut butter is made right there with a nut butter machine - so you can be sure there are no additives or ultra-processing.

If these guys also started selling sauces like ketchup or mustard etc, where I could fill my bottle with them, I would absolutely get it from there. I guess most sauces can't be made on site, but its still a net win for the shop to get a bulk keg for them and customers to refill their bottles.
