I have gone into multiple establishments who sell e-cigs and vaping gear. First thing I do is check out their interest in the community.
If they are into selling the product they must be accountable to you and me. To me that means they must be a member of CASAA and actively participate in the local political arena also.. They have their business, and "we" are fighting for our rights, and theirs, (by default)..
I have been to those who don't subscribe, I and I tell them they are a joke of a business....
Would You ??
Yep, I sure would. I don't base my consumer decisions on what "clubs" the business owner is a member of. While I most CERTAINLY agree it is important to be a member of CASAA, I would never it hold it against a vape business for not being a member. I might even go so far as to ask if they've heard of CASAA, and why they might not be a member, but I wouldn't hold it against them.
I judge a company on their customer service, their pricing, their inventory & products in stock, and whether or not they have what I need. If they meet my needs, I am more than happy to shop with them.
Also, once I find a company that does well in all of the categories I mentioned, and I order from them successfully, having a pleasurable experience...I almost ALWAYS go back to them.
