I picked some up last week when I visited the store. I can't speak to the shipping costs they charge, but the four gallons of gas and the subway ride there and back probably comes to about the $16 people are quoting for shipping costs, so I didn't dodge the bullet, either.
According to the sales associate, Thanksgiving Day is a blend of six different tobaccos (mainly Burleys and Virginias I am guessing), with a "rum and fruit juices" topping/casing. It comes in a 4oz "crumble cake" that breaks apart very easily. I have smoked a few bowls of it, twice in a small bowl and once in a large bowl, and it is very good in a small bowl but is outstanding in a large bowl. It didn't seem too moist so I didn't dry it out before smoking it. It burned very cool in the large bowl, and a little hotter in the smaller bowl; probably a function of the pipe and not the tobacco. Each experience provided a moderately rich smoke; I wouldn't call it creamy, but it was fairly thick and each time it required no re-lights and burned to a fine white ash with no remaining dottle.
I wish I could give a "Jim Inks" quality review, but my palate is not that sophisticated. I can tell the difference between Burley, Virginia, Perique, Latakia, etc. but when you start mixing them together I can get easily confused. I did detect a very faint floral flavor on the initial light and for perhaps the first quarter of the bowl, but then it was gone thereafter. I personally could not make out a "Rum" flavor, but there was definitely a very mild fruit sweetness. I can't make out which fruit (i.e. It wasn't strawberry or pineapple, or cherry). But it was very mild and made it a nice change of pace as I typically don't smoke aromatics. I can tell that the quality of the ingredient tobaccos is very high, and this is quickly becoming one of my most enjoyable smokes this season. I plan on getting this every year from now on as long as it is offered. This is the perfect season for this blend, in the same way we drink eggnog or eat pumpkin pie at certain times of the year and not in other times.
When I was at the store everyone there (including the customers) was very pleasant and helpful. I am from the greater Boston area, so maybe I am immune to some of the personality issues that people are describing, but I have only great things to say about Peretti's customer service.
My opinions only!
