Geoff -- you mentioned in your 2oz doubler post that the electronics were "Get you by" pieces, not "quality" pieces.
I'd like to add one other thing that I think they're great for; Newbies.
I've had a few friends that have wanted to try ecigs but were put off by the initial pricing. I've since sent 2 to your site and ordered one "made myself" kit for a friend and ordered it for her. 2 batteries, and a wall charger for $16. Who can argue with that and a 1oz bottle of whatever is on sale.
For $26 they can have a "trial kit" or a non-sale flavor instead for $31 total. I think it makes it a LOT more palatable for people on the fence about
vaping. The only thing I'd add and I'm sure you'll hear it more is cartomizers. For a newbie they're much easier. Less hassle to refill, less parts, etc. I mailed her one of my own packs from a carton I bought.
I know you don't want to become an "electronics" store but I also know how big you are on encouraging people to switch to
vaping instead of killing themselves on analogs and I know from talking to many friends and acquaintances that cartos are much more attractive to many of them. Even if you sold a 5 pack for $8, 9, or even $10 I think many people trying it for the first time would grab a pack for the convenience. Anything that makes it easier for a first timer to get into
vaping is good IMO.
Just a thought.
