To my knowledge, they're all the same price. We've been to several around the area. However, we have also found them to be disasters. They're packed...and I mean packed like MK packed...dirty, and just not great places to be. The checkout line takes forever. We very much prefer Target, even though we pay a bit more. They're not crowded, clean and easy to check out. If we just want groceries, we usually go to Publix. Same deal...a bit more expensive but far less hectic.
This probably sounds goofy, but I get excited to shop at Publix when I’m on vacation. Haha! I think their stores are clean and their food is fresh. I also love their deli items. I don’t mind splurging on boars head deli meat when I’m on vacation. I figure I’m still saving money over eating out every meal.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.
