WILL TRY to reply to first Q. I had used V2 and really liked their products but their shipping times and methods sure left a lot to be desired !! I had orders sit for 2 wks or more in their warehouse before being shipped after being paided for to come fed X!! I WAS lucky enough to find Vapor4Life and have never looked back!I HAVE never waited longer than 5 days from placing an order with Vapor4Life till its arrival at my home..most of the time its here in 3 days. THAT IS important to people like me who have the the bad habit of letting my supply get low before i relize i need to reorder.ONE OTHER thing Vapor4Life will give the same service for small orders(25.00) that they give to the large orders(200.00) I KNOW this as a fact because i have placed an order for both and received the same great service...also you can use your spare V2 supplies on Vapor4Life too.
