I've had good luck with health cabin also. Along with them, sourcemore and everzon I've placed several orders with and have had decent shipping times. The smart China vendors are shipping using 4px into the states and then transferring the packages to USPS. However, that will end soon.
I have considered selling some stuff. More so stuff that I bought than review items. Doing reviews has helped me get out of my rut of only black, silver, and gray mods. I love the red argus gt that I bought. I did buy some stuff though a year or so ago just to stock up that I don't know if I'll use or not like the 200 kanger clapton coils. I thought if I didn't have anything else and couldn't build rtas that I'd have those but I honestly don't like the kanger tanks very much any more.
Just a reminder that Heartland has been shipping UPS for my last couple orders of nic so the usps thing shouldn't really affect them for getting nic but I have a feeling that the free shipping will end and prices will probably go up. With the liter I just got, I have about 10.5 in the freezer. That should last me forever.
