Concerning the e commerce issues and thePayPal review issue:
I had a chat last night with an old time friend and respected mod maker concerning this and what he told me is the following:
1.) e commerce issues: The e commerce companies are very weary about anything ecig related as they are afraid that they might get involved when somebody buys a mod and/or juice and that person is not actually 18 years or older as the age verification on most websites don't mean anything. Also as it is a very young industry with little information about risks, health, regulation etc. they hold back on supporting anything ecig related. Some of the ecig vendors he knows of are actually registered as totally something else: like a machine shop, carpentry, wood working shop etc... and therefore they are not being harrased and/or denied to sell their merchandise.  All this is only related to USA vendors, in Europa there is no issue at all (f.i. Totally Wicked has a big shop in the USA, but there "mother company resides in the UK).
2.) PayPal: same as above but the trouble you experienced lately most likely was caused due to the fact that within a 10 minutes time a big amount of large transactions went through PP and that triggered there alarms. It is very said to see that with a spontaneous action from your side to have the AYS mini's made available actually caused your PP account to go under review. Well lessons learned here I suppose and I really hope for you and everybody this is going to be solved very soon.
I hope I make any sense and that you can do something with this information if you are not aware of this already.
kind regards,
