I will probably want a gallon of milk and a case of water for our stay. I was thrilled to find Garden Grocer will deliver for only $10 - less than the taxi fare to go to an off-site store and back. But, now I'm reading that some of the resorts have grab 'n go places where I can get these items for a fair price. I'm staying at Pop, so I don't know what they'll have in their grab 'n go. What do you recommend? Also, If I use Garden Grocer, do I give a tip in addition? How much for a tip on a $20 ($10 food + $10 delivery) total?
