I've never heard of that service.
However, we have faxed our order to Albertsons which is a grocery store that is right off the highway from the airport (you can see it from the highway, next to a Home Depot I believe).
We fax the order down the day before we leave (I call first and let them know I'm faxing). Then we stop (DH and kids don't even get out of the car), I go in and pay and they bring it out all bagged. Takes about 10 minutes.
One time we were able to get right into our room, the other time our room wasn't ready yet so VWL put all the bags into refrigeration for us. Then they brought it all up with the luggage later. It worked out great.
