Hello. I'm traveling to Puerto Rico the first week of December 2018. Due to a pre-existing RCI membership, I'm lodging at Palmas del Mar. Since my lodgings include a kitchen, I will need groceries. I'd like my vacation dollars spent to stay on the island rather than going, say, to Bentonville, Arkansas, so I'm wondering what the options are to shop local for groceries on the eastern side of the island. Are there any Puerto Rico-based grocery stores or store chains, or should I expect to make multiple stops in an effort to find locally-owned meat markets, bakeries, the farmer's market, and so on?
My geographic focus for this is probably going to be centered on Humacao, but I'm willing to drive a little further if it helps out a local entrepreneur rather than a multinational conglomerate.
Your help in this is greatly appreciated.
