I think that is more of an ad justifying why to participate in today's sale.
That being said, I am certainly not a believer that you can't make a good stick for an affordable price. I enjoy the full range from smokes that I find are a great deal for the money to "luxury" smokes. It comes down to I smoke what I like. As Daniel pointed out, there are cost differences in certain leaves due to availability (or lack thereof), age, region, etc. There are also differences in labor costs, factories and/or tenured rollers that would factor in as well. Marketing and cache are certainly big factors. We all know the big boys make their living off of the casual smokers walking in and recognizing Cohiba, Romeo Y Julieta, and Montecristo and buying based on the name. To me that shows that the little guys are making their name through putting out quality smokes and getting their word out through the cigar community in order to make it. They are making something that is different and presumably better, or we would all be buying $2 bundle smokes and have nothing to talk about on here.
I admit it, I fall for looks sometimes. I find myself drawn to certain releases by looks or hype. Now I don't stay around if they disappoint, but I won't lie and say I have never been drawn to a cigar because it looks cool or like something I want to try.
I have had $25 cigars both wow me and disappoint me. I have had $4 cigars do the same. To me, there does seem to be a sweet spot in that $10-15 MSRP that more often than not consistently delivers quality tobacco as well as quality construction. All the better when you can grab some of those at a significant discount.
So I guess I would say that I disagree with the statement, but there is some validity to it. I just don't think you can make a blanket statement that due to science even these bundle smokes should taste the same as an Opus X. Again, as we have all said so many times, the most important part of this hobby is to smoke what you like and like what you smoke. If you truly like and enjoy a $100 Cuban Cohiba LE and that justifies the spend for you, then nobody can tell you that you are wrong. Conversly, if you have a cooler full of $2 seconds and to you they taste the same and it makes you happy to smoke good cigars and save the money, you too are correct! That is the great thing about this hobby. Literaly thousands of choices out there to smoke and you are not required to like or dislike any particular one of them.
