This thread is a bit funny.
Sometimes beer nerds think everyone knows about the beer they do and I need to remind them how they are a small subset of a subset.
So far every beer mentioned in this thread, including Dogfish 120, Heady Topper, and even Westvleteren (the 12 is the one you want they also make Blonde and 8 for retail), have been basically normal beet or 'shelf turds', stuff you can just walk in and buy somewhere at the right place or time of year.
The Westy 12 got a gift box set with two bottles and a glass released a few years back and even the straight from the abbey stuff isn't that hard to get because it gained some attention as the 'best beer in the world' some time back so plenty of Belgian beer webshops always keep it in stock.
Dogfish 120 minute sits because it's no longer special and Heady Topper is also an easy get if you have connections in the northeast.
People trade for beer, regularly shipping 50 pound boxes around on FedEx trucks acquiring, flipping beer for better beer, winning trades, posting haul pics. Going to release days, bringing their girlfriend/parents/grandparents/bums/hookups (none of those are jokes all have happened) so that they can get extra allotments when the release is limited to say 2 bottles/cans per person.
The hype train is real and drives the perceived value of certain beers/breweries
If it is either a limited release adjunct laden stout, a hazy/New England/Northeast IPA in a 16 oz can, or a Belgian Gueuze (a traditional sour ale) those are generally the most desirable with prices on the secondary market for the stouts and gueuzes easily reaching a few hundred bucks and topping out around $1500 for some rare shit for a single 22oz/750mL bottle.
Otherwise the beer market in the US on the micro/craft/independent side is hyper local, brewpubs are thriving and I think we are over 6,000 breweries in the US.
Much like SNES prices, it will probably all come crashing down soon.
Lots of shared qualities between hobbies of all kinda when you get into the tail end of the bell curve.
