Youch, that was a pretty rough advertisement lol. Many were saying they got an apology letter, that it was provape's marketing team that did that and they didn't approve it or something along those lines.
It's true if you shop around there are much better deals online. Like the istick mentioned, some places sell the tc100w for $40 or so while others sell it for $30. Not sure what local b&m's sell it for, my local shops in general are a bit meh. A friend of mine went to her local vape shop and managed to get ejuice that didn't look right compared to mine I'd just ordered. Come to find out the born on date showed the juice she bought was a year old already. On the bright side it was likely well steeped lol.
Makes it tough for local businesses unless they really put forth the effort but the same can be said of just about any industry. How does a local mom n pop auto repair business compete with the likes of chain operations. Your locally owned/operated shop is having to pay retail for the parts (wholesale is a joke, like $0.30 less than full boat retail to the public) and they tend to use better quality parts like brake pads. But when you're competing with someplace like midas that's buying boatloads of cheap pads through the corporate office so they can sell a $50 brake job with lifetime warranty, explain to your customers your $120 brake job isn't using crappy low tier pads and that midas likely isn't putting akebono's on your car for $50.
It's a cutthroat world out there and too often money talks.
