Arlington Pipe and Cigar features a selection of pipe tobacco that rivals Iwan Ries these days and has an exceptionally broad selection of tobaccos sold by the ounce. I don't believe they ship though. Very nice people, too. They are the home of the Chicagoland Pipe Collectors Club and they treat us like royalty.
The pipe selection focuses on the mid-market brands, like Peterson, Savinelli, but carry a small selection of artisan pipes and also Morgan Bones. For a larger selection of artisan pipes and luxury brands like Dunhill and Castello, Iwan Ries is the place to go in Chicagoland.
Excellent cigar selection, too.
Being an Illinois retailer, prices are necessarily higher than most online retailers, but with rare exception, if they sell a blend I want to buy, I buy it from them.
I do not recall seeing the specific McConnell's blend that was asked about.
