TICO and the French Deli are both excellent choices for provisions. There's also another wine/liqour store just up the hill from Riteway as well as the bulk store next door to them. All walkable and depending on how many crew are going to be humping provisions, might work.
But as was asked.....why?? The only beer I would want to see after travelling all day is a frosty one on my hand, not a flat of warm cans up on my shoulder as I march back to the dock. C'mon Cappy, time to play the 'rock, paper RANK' card.
