How does the shop of cuphead work?

Heading into cuphead, I heard that the shop works in a weird way.
I heard the shop works in branches, where if you buy item A1 you'll get A2 next, but if you buy B1 you get B2 next. So you must make sure to buy the right items to get the right endgame items.
I also heard that there's not enough coins in the game to buy everything, so if you want certain upgrades, you must buy the ones before or you might not have enough at the end to buy the upgrades you really want.
Is it really how the shop works? Also, if it is, what are the branches?
Best Answer
I believe there are deterministic branching paths in the shop based on my two playthroughs, although I can't find a full mapping of it. I'll figure out the mapping on my own in a few days.
To the more important of your two questions, you absolutely can purchase everything in the shop using a combination of Run 'n Gun levels, hidden coins, and NPC interactions. There's even an achievement for it, Butter-and-Egg Man.
