Thank you all for the advice, tips and links! I made shortcuts to the ones I don't have. It isn't the 1.6's that are getting hard to find, rather the 1.8's at <$10 Yes, every time myfreedomsmokes has a sale, I buy the max amount but I'm starting to get skittish and want to stock up on the 1.8's. So I'll buy a couple of packs here, a couple of packs there, before deciding where I'm going to buy enough to qualify for free shipping once month until I stop.
Btw, Jackie hasn't touched her authentic, $150 K4 since getting a Kabuki for Christmas, the first week of December.
Get this, went to a B&M about 23 miles away and asked if they had Nautilus coils. Kid says, "I'd have to see one, they come in all different sizes." Never mind...

Like Jackie said, they're not going to be real if he has to see one...
