For good wine, arbitrarily $20 or more, Select Wine is the place to go. Get the coupon from the web site and save 10%.

We get our cheaper wine at Super U, along with meat and almost everything else. They also do 1 to 1 for cash.

Gas is cheapest at the Cadisco on the Lagoon between Marigot and Sandy Ground. It's 0.89 and they do 1 to 1 for cash. The government did just lower the rates on the Dutch side, but some stations have ignored it. Moreover, they play funny games with exchange rate at times. That can't happen when you buy gas 1 to 1. Delta Petroleum also claims to do 1 to 1 at all locations.

Having said all that, it's probably not worth more than $3 on a 10 gallon fill-up.
