Best selection and Prices for Groceries and Liquor

We know about Sam’s Club, Soriana’s and Bodega…. I had read that on some items they upcharge due to tourists?
What are the best recommendations.
Thanks

I wonder where you read that? In my experience there is no difference in pricing for locals and tourists. Each of the stores you mention carry different things. For Sam's you need a membership, for Soriana and Bodega you don't.
