I never feel bad about not spending much in a vape shop... It's usually best not to mention Fasttech or any discount on-line sources. The staff tends to shut down and get a little miffed...
Now that I've gone DIY on juice though I have a real hard time kicking out the retail price most places charge. Oh and for the shops that make their own juice flavors... Geez forget talking shop on flavor mixing. It's like you are asking them to disclose National Security secrets...
