Here is an article I found on the developer forum to help with your question: Saving a folder full of stats through Datastore

I believe it would be smart to make a table of BoolValues to determine if the player has a shop item or not. And then save those boolvalues with a datastore. I would personally set it up like this:

Shop = {
    Brick = false,
    Wood = false,
    -- continuing
}
