Just went to this place today. I saw it a few times but it was always closed. Think they either recently opened or I was just unlucky with my timing before. Its a new brick and mortar in the Siniawa Plaza 2 in .....on City. Right by the head shop, EB games and a 5 guys burgers and fries.
They have liquids, and clearos with liquids set up to try before you buy, plus all kinds of batteries, mods and rebuildables. The guys who worked there seemed pretty cool and knew their stuff. If you're in NEPA and run out of liquid before your next shipment arrives might be a good idea to head over to Vape Boss and check it out.
Also the liquids that they mix in house are pretty darn good.
