I don't have 7, but I have a few: 2 for juice, but maybe 3 if I decide I like the new flavors I got; 2 for cartos, unless they are OOS or I find some on sale; 1 I used to buy these little clearos from, but I don't use them much anymore; 1 for attys; and 1 for batteries. That's for my on-going supplies.Oh cr@p! 7, maybe 8! LOL! I occasionally try something new, but I wait for sales.
ETA: It was posted that people wanted to know the names of the vendors, so here are mine:
Juice
Vixen Vapor
ECBlend
Cartos
Smoktek
IBTanked (I love their tanks and they also have standard size flanged Smok cartos that Smoktek doesn't)
CE3 XL clearos
Vapor's Choice
LR306 attys (bulk)
Vapor Kings
Batteries
RTD Vapor
I've ordered from many other vendors, but these are ones I have used at least 3x. I can't think of a vendor I have personally ordered from that I don't recommend.
