Love how much onboard you are with predictive pricing. One very important thing to consider here is that we are in argentina, in buenos aires, and prices change constantly. Especially if we account for inflation and USD rates. Can we somehow throw those in to the mix as well so that we have a clearer picture of how much things actually cost in argentina? I would say the proper anchor is USD price, since like I said, argentina loves USD. Besides this, I am wondering... wouldn't these supermarkets all have their tomorrow prices set somewhere? I wouldn't guess that they just set it daily, most probably they have some kind of preparation! And finally in regards to this, we don't have to start counting now. We could already either see if vtex allows us to pull data from previous days, and if not, maybe we start building something based of SEPA? what do you think? again don't do, just think and provide feedback.
In regards to my coordinates, here they are properly: 
34°34'12.0"S 58°26'56.4"W = aprox -34.5700, -58.449
In regards to this, still consider markets with an online precense like changomas, disco, vea, jumbo, etc. that I might not be close by but as said, I will potentially be buying from them online if it is worth it of course.
I guess the location is only really useful if I need one or the other thing but not for the automated supermarket purchase right? In that case we can keep the same as we were doing before I introduced the location restriction. Let me know your thoughts.
about phase 2, thank you for sharing these. I am now much more reassured.
about the plan:
1- yes but only for the "near-store" UI only! Like even if I do not have any VEA or Jumbo or disco or any other close by, I would still like to know their offers if they are online! like, based on the ones we already have a scraper. you get me?
2- lovely
3- lovely, but should be one entry per EAN no? or wait.. because of the same EAN for idfferent packages, that might suck! ahhhh idk how to fix this part honestly because obviously I want to know the price of all items but if EANs are not unique then idk
4- lovely, but also lmk about whats written in this message first.
