Tried to do some multi-quoting action on my phone and subsequently got frustrated. The gist of what I was going to say:
Selling beer on the secondary market, and trading with the purpose of extorting max value out of your beer probably aren't that different. Thus you see a lot of people who are completely turned off by both practices. The key differences are probably that,
1) Reselling on the secondary market is illegal (then again so is shipping) and;
2) Even if someone trades for quantity or max value, while possibly annoying, at least presumably they're trading for beer that isn't available in their local market.
What
barflybastard mentioned would probably be the most "pure" version of trading, and the least icky.
For me, trading is not the same as selling. Trading on some level is sharing--offering a product most likely not available to someone else, who has something mutually deemed to be of comparable value that is not available to me.
What people need to realize is, even if they can justify reselling their beer for more value for themselves, they are driving a higher price point for the beer which could come back and bite them in the ass.
Take Voodoo, as an example. Clearly against the practice of reselling their beer for profit. What if they had sold GNVP for $50 a bottle this last release instead of $20? Or BRC4 for $400 instead of ~200? Sure, we would all be pissed, but the beer would probably still eventually sell out, albeit much more slowly. Now the added value of demand goes into the hands of folks who labored to create the beer instead of some schmuck who waited in line for a couple hours. As an employee-owned company, Voodoo could even justify this as a noble effort to put more earnings into the hands of the employees, and feel pretty good about it at the end of the day.
Every "whale" has some price point where it will turd on shelves, waiting for #newmoney to casually buy it at their leisure.
Bottom line, we all get to enjoy Voodoo Barrel Room beers at below market value because they choose not to reap max value from us (customers). Don't be the D Bag that tempts them to put that $ into the more deserving hands of their owners, instead of guys that flip a $20 beer for $175. You will not like the result.
