Aero bars in NCC Delaware or surrounding area
Funny you should ask about that :-)
I love Aero bars as well, and just yesterday I happened to see them on the shelf in the "international" foods section on Wegman's in Manalapan, NJ. Needless to say, several ended up in my shopping cart. LOL.
Realizing that is not close by most folks' definition to northern Delaware (even if you *really* crave 'em) but you might try one of the Wegman's in the Philly area ....
Hope this helps !
