I purchase my boxes online, which has only been 2 so far. I buy singles from local B&M's. Once i start developing a better palate, I may purchase singles online if they are cheaper.
90% on line and 10% the local B&M. I like to support the local shop as much as I can, but the price difference is hard to swallow. I like to pickup a couple of sticks to try that I might not even look at on line. They also have events that are fun to attend.
I have never bought any cigars online. I have bought some lighters humidifiers, I think the best part of buying cigars is doing the shopping. I feel like a kid in a toy store when i am in a bigger cigar store like Holt's.
I tend to split it fairly evenly, it just depends on how lazy I am as to whether or not I stop by the B&M. There are also a couple of my favorite brands that I can only get online.
