Yes. My experience had been that you can get better deals on cigarbid but MMAO has some stuff that cigarbid doesn't. If you are inclined to try it I would suggest the following:
1. Start low, if the same lot is offered on cigarbid, my experience is that the lowest offer they will accept is the quickbuy price, however, you should start lower just in case. Jambalaya or daily deal pricing is something else you may want to use as a benchmark, but see #2.
2. Remember to factor in shipping since you can get free shipping on most CI products.
3. I would use this if I am impatient and don't want to wait for cigarbid or to bid on higher end stuff to see if I can get a deal. I've gotten Perdomo Edicition de Silva's for 10 bucks a piece on MMAO.
Good luck and keep us posted if you do it.
