I suggest joining a local whiskey club where you can get someone to give you a sample or trade for the bottle.... Or, work your way around to all your local independent liquor stores. You can find them at MSRP if you look enough. It's generally only released once a year and Buffalo Trace drops most of its best releases around the holidays, so now's the right time to keep an eye out for one.
There's just too much of any version of Blanton's out there to justify paying the secondary market prices (current is $200 - $300, market average is $280, MSRP is $150). Worst case, come to Dallas and I'll crack my bottle open
If you're in Burlington, might stop in to
The Whiskey Room or
Prohibition Pig in Waterbury Village and see if they have a bottle at the bar.
