I have never done it, u really have to plan. AF guys seem to have the system down alot better and take advantage more. The base line health care is pretty good. If ur in an area without specialists u can go off post. The PX is no bargain unless its big electronics..no tax but AFFESS sucks. The commisaries are pretty good but it depends on where u are. The one at Riley sucks while the one on FT Meade kicks ass. The food is cheaper and the bigger the store the better the chance that u will get the same choice at the best supermarkets. They are on pare with a super walmart. That said I don't shop at mine alot. They're talking about transfering GI bill rights to dependents. Some colleges will give u free instate at some schools. Ohio is one.
