I've had a pretty good long term experience with Ok Vapor. Their prices and selection are solid, the staff are helpful and polite, and they have loyalty programs, buy X get X free promotions and the like. I'm a pretty casual vaper, just meeting a basic need since I quit smoking, but I've had a great overall experience. Not every juice I've purchased is a winner, but on the whole they've got me as a customer and they've earned it!
