To the bolded: Publix is pretty pricey, but on vacation, you might not mind. We have one around the corner--I check out their weekly flyer, but seldom shop there. On the good side, they don't require a loyalty card, and their BOGOs are pretty good. We also love their made-to-order subs, and their store brand ice cream is very good (black container). On sale, it's 2, 1/2 gallons (true half gallons!) for $6. But, aside from cherry-picking specials, it's too pricey for me to shop there. However, they're very close to WDW, and the OP may not want to spend the entire vacation chasing the absolute lowest prices.
