Closest but depending on the time of day, traffic can be a real headache on 535 (Vineland Rd.) at the exit from I4 and back on. Also a bit of an older store.
Newer, larger one on Turkey Lake. A bit farther, but traffic not as big of an issue although a bit harder to navigate to from POP.
Also one (farther away) on 27 (Clermont) at the end of 192 West. Traffic can be a real headache on 192 though.
Another one on 192 East but traffic horrible.
