We've done that a few times.
(Bought a grocery store prepared meal.)
One time was great.
Another time was a bit of a bust because the bird wasn't done, so we had to spend more time than expected cooking/warming it.
Another alternative is to buy a meal from a place like Boston Market, but it's hardly the beautiful spread that a real home-cooked turkey can be. :-)
Good luck Laura! AG and DK won't lead you astray.
Cheers,
Scott.
