You don't get more local than your own wallet. Sure if something is the same price then buying locally is better but as soon as you are paying extra then you are just giving your cash away.
True, but there's a premium that some people are willing to pay to actually shop in a store. Some people just like to pick the item up, ask questions about it and perhaps even try it. Good customer service is worth a little extra.
Then, there are shipping costs and time to consider. FastTech, which is now delivering products in 7-10 days, offers free shipping. However, other vendors aren't able to do that.
Then, there's the satisfaction of taking it home and using it right away, rather than waiting for Vapemail to come.
Is all that worth a 300% markup? Not to me.
I can get genuine Kanger, Joye and Innokin equipment at my B&M for what amounts to a price equal to online cost plus shipping from a stateside vendor, plus a premium of anywhere from $2 to $7, depending on what I'm buying. That, I'm Ok with.
