Hello, I've been using a local store in my area for heads,batteries,liquid, etc. I thought the prices were decent until I started seeing some of the prices from online vendors. I looked on mad vapes website and found a BDC glassomizer for 9$ on sale, my question is if mad vapes is safe to buy from or not? Also, I've been paying 5.99 for 10ml bottles and 15.99 for 30ml bottles of eliquid and was wondering where I could get it cheaper online. Another funny thing is that the bdc coils sell for 9$ (for a 3 pack) and I have found some online for 3$ for a 5pack!
