I've been pretty forthright with my disgust at Dicodes-USA, but it's only fair that I mention a (possible?) good thing about them.
Since they appeared maybe two years ago, for their office they listed an address in California - Covina as I remember. But googling that address showed that the location was for a company who sold portable air conditioning systems. So either the vape business was a backroom hobby sort of thing or there was intent to hide their real location.
During this latest thread, I now see they've changed the address they list on their website. The address comes up as in a business park but no tenant is listed. So there's some chance it could actually be their headquarters. Considering their past performance, I'm not convinced it's not just a better effort at trying to appear legit.
As for the stab mod availability, I'm not sure if things have somehow changed but I do know the mods have always been available for the dealers to buy from that Dicodes stock, and carry in stock at their own location. When I bought my stab Dani from Creme de Vape, it shipped the same day from the UK. Some stores may not wish (or be able to) tie that much money up and there's where the preorder thing arises. No crime there, but I would expect a company to be open and honest about how the transaction will be handled.
Georg was the person I've dealt with at Dicodes and is great, taking care of any questions or issues I had. I think his response is saying that the pictures you saw may be theirs, showing the dealers what is available - or the other option of being a dealer showing the mods they've bought and received. Considering my past experiences with D-USA, I lean strongly to the first option.
