I want to make a realistic shopping part in my game, I want the player to go to different shelves in the store and pick things to buy. I am completely unsure of how to do this. I can explain more in detail exactly what I would like to achieve in part of my game but at this point am still unsure of how to even make this work.

For classic settings you could display all items in shop as events, with a confirmation to outright buy it (posed as a question from the shopkeeper) or grab it to "pay at register" the latter would include a switch/variable flipping to add a price and item to be added once the player goes to the checkout.

In the case of shelves on a more modern setting having multiple items you would need a text explanation of whats on the shelf, their price and ask the player what to grab for their shopping cart/basket then adjust switches/variables as needed adding price and "to be added to inventory items" properly organized so when player pays for them the money gets deducted and the items added properly.

Its a tad more complicated on the long run than simply adding a shopkeeper with a list of sellable goods or the display items and buy example above as you will require variable/switch management to make your own shopping system, totally doable on the base maker though.

For an even more basic version than that: just put an event on each shelf in your shop. Make that event pop up its own shop processing with only the items you want to be on that shelf. Easy peasey.

Hello welcome.
Will the player have to go through the cashier to pay at the end?

JRPG games in general are based on times before the industrial age, where this concept of the customer being able to touch products before purchase did not exist.
In this concept you want to remember a little GBC Zelda games:
Where the player took the desired item to the counter, but it was possible to trick the seller and rob the store, but the consequence was too bad. I just commented because it's really the only game I remember having this mechanism.

Another thing that would lose the sense of realism would be the ability to buy 99 of each item and get them all, and that number wouldn't even fit on a shelf.

Another thing would be that after the purchase you would have to wait a period of hours for the merchant to receive a new shipment of items.
