Willowsong -- the m401 carts will fit on the Blu. You can order blanks for the m401 from Ruyan direct (Heaven Gifts) among other places. Vaporstix sells the m401 and is a US vendor (both are supporting suppliers here). I'm not sure if Travis at Vaporstix has the 401 carts yet though.
I've fallen in love with Eastmall. I'll wait the extra time, and if the prices were higher I would pay them. Their service is simply unmatched in my book. If they have it - that's where my money will go.
But thanks for the tip. Even though I'll probably retire my Blus as emergency gear, I would like to have some empties on hand with caps. If I feel that urge for an analog - that's where I'll go.
Also about the suspicions...I can understand the leery view a lot of veterans have. It can certainly seem that there are a lot of Blu employees here. Also try to understand that Blu had some crazy advertising going on and a lot of people found out about e-cigs in general as a result of that advertising (including me). They may have some shady people on here, but I would venture that the majority are just new users excited about e-cigs for the first time. In a way, it actually benefits the other suppliers. As a result of stumbling upon a Blu ad and beginning my investigations into all things e-cig, I have now ordered lots of stuff from Travis at vaporstix.com, lots of stuff from Ruyan and now, as a result of Terraphon's review, a 510 starter kit from e-smokey treats. If I hadn't found Blu, I might not have found out about e-cigs for a long time....so, in a way, it's because of Blu that I've spent so much money with some of the other suppliers around here.
I don't discount the possibility of spammers/people working for Blu... but there are also just a lot of new people too. Because of that, I think it was very understanding and gracious of SJ to give people interested in the Blu a forum to talk about it. It might have been better placed in the Specific Model Review subforum... but at least there is a place for it. I am thankful to SJ for that.
I really doubt that there are Blu employees here. Affiliates? Possibly. Troublemakers? Definitely. I still hate being lumped in with them and I'm certain people still view me that way. It's not going to stop me from helping out newbies or answering questions. More voices can only help us.
