taryn said it best--since this is *actually* the V4L subforum it's just a courtesy not to 'recommend' competitors for the same products they carry. but that said, if you weren't aware of the KR8 model specific discussion, you had no way of knowing. also, i'm sure if anyone here uses another company, they will pm you that info.
i
haven't cause the only companies where i've seen 'better deals' are the big bulk chinese companies, and i prefer my $ to go to V4L since they've taken good care of me as a customer.
i'd ask your question here (click>)
KR808D-1 - E-Cigarette Forum
or, i'd go to the approved suppliers list here (click>)
ECF Approved Suppliers - E-Cigarette Forum and check out the chinese companies (they have a CN below the company name in this list), as going on my *own* searches, they have the lowest prices on stuff in bulk. i haven't used them, but i'm sure if you check their sites and see a good deal you can come back and post in their subforum or the KR8 subforum and ask for reviews of their products and service from other members.
