LOL. How many you have now? At that price they are in the spare parts price range.Likewise, Robert, and I think most of us here are as well.
(Although I did bite on those $7 KFs from Fluid... another 6 headed my way!)
I did pretty much the same and ordered another 10 T3S's last week.
I already have 15 now and still using the same 4 I started vaping on about 10 months ago. So I should be set for 20 years or so on T3's.
And I have 40 or so coils to rebuild forever.
