I'm not sure if it has already been suggested, but I have a few ideas as far as combos/kits.
1) X2 Starter Kit - include a battery, and charger/wall adapter, and could possibly include 5 prefilled cartos and/or a bottle of
juice along with 1 or 2 X2 clearos or T3 Clearos, and maybe a cone option
2) X2 Advanced Kit - 2 X2 battery and charger/wall adapter, and could possibly include 5 prefilled cartos and/or a bottle of e
juice along with 1 or 2 X2 Clearos or T3 Clearos, and maybe a cone option and a case
3) Spinner Express Kit - a Spinner battery, charger/wall adapter, 5 prefilled cartos and a cone
4) Spinner Starter Kit - Spinner battery, charger/wall adapter, 1 or 2 t3 clearo, bottle of e juice, and a cone
5) mixed starter kit - 1 spinner and 1 x2 battery chargers/wall adapters, 1 x2 and 1 t3 clearo, bottle of 3 juice and 2 cones.
6) Passthrough Kit - the passthrough plus the 1.5 amp wall adapter
7) charger combo - charger and wall adapter (possible 1.5 amp wall adapter upgrade)
8) car combo - charger and car outlet adapter
9) complete charge kit - charger, car outlet adapter, wall adapter (Possible 1.5 amp adapter upgrade)
10) THE WORKS! - 2 regular batteies, 1 x2 battery, 1 spinner battery, 2 regular and 1 spinner charger, 1 regular wall adapter, 1 1.5 amp wall adapter, 1 car adapter, 1 passthrough, 1 pcc, 1 xl carry case, 1 regular carry case, 1 e juice bottle, 5 prefilled cartos, 1 mini clearo, 1 nano clearo, 1 x2 clearo, 1 t3 clearo, 1 t3 mini clearo, 2 cones.
The ones I would most like to see would be an X2 kit and a spinner kit, and a combo for the charger plus wall adapter, the rest I just think would n nice too see
