We have a car service pick us up (sorry, can't give name, banned ) and they give us a 30 minute grocery stop (we prefer Publix's) and they run around 100.00 round trip.......
We figured that's not bad since a taxi will run 40 bucks plus tip each way so fo the extra 20 dollars we get personalized service, not a cigarette smelling, filthy cab, and 30 minutes at a grocery store.....
Not into delivery services....fees too high, we don't need that much stuff, the real money savers for us are drinks (soda, beer, wine and alcohol) which are excluded in delivery services totals......
Seach the web, companies that will pick up in Kissimmee will come up...most prefer Orlando but there are a few that do do both...good luck!!
