If you have a car I'd just run to Winn Dixie or Publix. We did not have a car this trip. For me Walmart was the cheapest and easiest website to use. Garden Grocer does this all the time so their delivery process I feel goes more smoothly more often but the prices are astronomical. I think if you are prepared and know what to expect Walmart is fine. Yes they will deliver to bell services. I wasn't sure how it would work but it just did. They had my groceries on their own shelf and then I also had a shelf in the fridge where they had all my perishables. Bell services did a great job (we were actually at All Star Sports and pretty much everything there was a hot mess and they still managed to do a good job with my groceries). If you can actually be at the resort during the 1 hour window you set for delivery time that is even better and that is the ideal way to get Walmart delivery because it just saves a bunch of steps.
