so I have been shopping around for my wife as she would like to start vaping also. she wants a simple set up for now consisting of a ego battery (900mah) and a kanger evod and some coil heads seeing as how we have a few chargers laying around as back ups for my ego batterys. so I have been looking for the best deal and found a 900 mah ego-t battery on ebay for $12 after shipping and a evod for $5. should I trust ebay? or should I stick to somewhere like say discountvapers? or do you recommend any other great places.
