Where do you live people from bigger cities say the prices aren't that much higher. But from the midwest It is about double of what i'm used to.

We were just there in Feb and shop at Starfish Market, this year I kept a couple of receipts:

newman's salsa $4.59
can of albacore tuna $3.19
Garden of Eden Blue chips $7.49
Alfafa sprouts $2.49
baby carrots small bag $2.59
bag of mixed greens for salads $6.79
one large pink grapefruit $3.79 lb
Vermont Cheddar cheese $7.99
Oscar Myer bacon $8.19
1/2 gallon of 2% milk $4.29
fuji apples $3.79 a lb
loaf of 12 grain bread $8.49

hope this helps

Have been home a week and just received our final box that we mailed home from St. John and found another Starfish grocery receipt and thought you might want some more prices

1/2 gallon of Tropicana oj $4.89
Dole Bananas $1.14 a lb
Hawaiin Tropic 30 Sunblock 5.4 oz $7.99
Coffee mate French Vanilla (liquid version) $3.65

dinner on your terrace at the villa over looking the Caribbean Ocean in 78 degrees with a loved one PRICELESS

Remember everything is shipped in and you pay the price for it. Rum is dirt cheap but a six pack of soda costs $9.99

Hope this helps in your planning

Jill, we'd be good eating buddies. Your grocery list look exactly like one I might have!
You pay a bit more on the island, but groceries are still cheaper than eating out all the time.
