Here's where I've shopped online:

cigarsinternational.com

tophatcigar.com

gttobacco.com

lilbrown.com (picked up a box of MONTECRISTO PLATINUM POR DELACROIX - Tube for less than $95 shipped, now you have to call for prices so I don't know if they've jacked them up or what)

puroexpress.com (just ordered here recently but haven't received the package yet, I'm looking forward to it's arrival)
