The cups are currently available for pre-ordering from the Hershey's online store and will ship the week of March 24, 2014.
There's a price premium for the freshness though: It's $27.95 (plus shipping) for six dozen peanut butter cups (about 2 and a half pounds worth or about 40 ounces). You can get about 40 ounces of Reese's Peanut Butter Cups for roughly $13 in stores.
I'm guessing the main draw of these is that the peanut butter would be fresher and moister versus the (usually) drier stuff you find on the shelves.
If you're looking to get "Fresh from the Factory" Reese's Peanut Butter cups, they're only available for a limited time.
