You can find some good sales from time to time, but going with a quality clone (Infinite, HCigar, EhPro) are the most economical way to go, even if not on sale.
I spent ~$34 each for my three MODS (including shipping), and my Copper Penny from HCigar is so close to an authentic, it's scary! I've compared it side by side, even interchanged the parts... zero differences!
Personally, I'd probably not buy an authentic unless the price was insanely low. I'll keep buying quality clones, and looking for good sales on those when I can find them
