IMHO, it is a horrible ideea to send someone there to buy cigars for you. Over the top expensive when compared to anywhere else EXCEPT other Vegas retailers. The house brand is unique and pretty good but again, not worth the $$$ IMO. ANd truthfully, any cigar you can buy there you can trade for here (with a few notable exceptions of course).
Now, if you are in Vegas and you are a cigar smoker it is a MUST to go there. I found it a great way to spend a couple of hours. Hold your nose at the $$$, buy a house brand cigar or two, order a Mojito or two and sit on the "patio" and people watch. It's a great time. I know it is a must visit anytime I am in town.
To summarize. Sending someone there to buy you stuff other than the house brand and certain very very very HtF's----BAD.
Going there to spend a few hours......VERY GOOD.
