Depends on the price they want for theirs. Where I live there isn't a real vape shop within 30 miles of me, also work nights, so it is impractical for me to visit a B&M most of the time. Not a fan of the 134, or own anything that only puts out 15 watts, but for the original price for the 134 could get two Hana dna30 clone mods.
Being vapers themselves, wouldn't worry about buying from them or not, sure they understand, like all vapers, the value of shopping online and maximizing ones vape. I'd find the best price you could for the gear you want, then go into the shop and say, hey, I can get it for this price at xyz, what kind of deal can I get from you?? Bartering can offer one great savings, and promote respectful discourse.
