Jason,
Personally, that isn't a bad deal. As you know from an earlier post, I would buy because I am looking to invest in a 510 Kit.... well they Cylon anyway.... but all the extras: atomizer, PCC, Passthru, USB Charger, etc, are, IMO, essentials that anyone who vapes must have. As a plus the charger/passthru are compatible with the 306 that I already have.
I guess you just have to look at it from both sides and see if it is good for your business. It really depends on what people are looking for... I mean, if people already have everything, they most likely won't buy, but if it were someone new to vaping like myself, then it's a good deal.
If it isn't too much work to add it to your website, and not too much of a profit loss to sell the kit like that, I'd say give it a whirl.
But please have the ultimate kit with the cylon

I am just waiting for it to be in stock on your website, and I will order it
Cardinal: I've been vaping for a little over a month as well... and I dunk my atomizer in alcohol once a week, I just never knew how to completely clean the atomizers out

Upon yours and Jason's advice... I just cleaned mine out with the qtip and alcohol and the taste is so fresh!

Thanks!!!
