I do not think that is correct. I rant and rave that people should take advantage of YS's pricing of those 2002 Tai Lian bings because they are innately good tea sold at well more than fair price, even though they are very dry stored. In a sense, it's the same with that 7542, it's just good tea at a good price. However, *actual* well-stored Dayi (even sold individually in anon CNNP wrappers) are well over $100 up to about 2003-2004 in the Chinese markets. Moreover, Dayi blends are fairly consistent. Anyone with enough tasting experience can distinguish Dayi from similar Fuhai, Haiwan, Kunming, etc, etc copies, let alone the odd inspirational single mountain or shop branded stuff like HK Henry or XZH versions. If it's some lost tong or three out there without that ticket, it will be easy enough to find a buyer who will give Dayi price, because that person can actually reliably tell the genuine product.
Well stored Dayi 7542 from '98 is roughly $300+. This isn't even talking about the blue water mark version or other special productions. Even if this one is *too* dry-stored, it's not going to be naturally $80 in any way shape or form. That's the price for so-wet-stored-it's-barely drinkable stuff. We're almost certainly talking about a random factory producing a 7542 and vanishing in the dusts of time. That does not mean it's bad, at all. Just like with the Tai Lian, it's a case of marketer-abandoned product. It's the duty of shopkeeps like YS's Scott and Ginkgo (not making any assumptions here) to do the work for their customers and select quality products. Guang from Houde, for example, does a very good job of digging out such products and making Frenchmen swoon over the delicacies he provides. If he puts something up, I don't care if there's virtually no identification on it, I'm just not liable to get seriously burned if I buy it unsampled, based on the rudimentary description and who's it from (not gonna buy Changtai, especially past 03, excluding that nice '04 Jinggu, for example).
Just concluding here by saying I could be wrong, and invite correction with absolutely no rancor.
