I'm relatively new to trading on here. I wanted to ask everyone's take on whether the trade below is fair: 1x SARA Cask 200 1x BA Torpedo 1x BA Narwhal 4x Pliny 1x Supplication For 1x BCBS Prop (2013) 1x BCBS Backyard 2x KBS (2013 and 2014) Thanks for any feedback.
Fair is in the eye of the eye of the beholder. It looks like you're fairly new to trading. Try not to get caught up in all the "What's the value of my beer?" nonsense that seems to have taken over this forum. No whales are being swapped here, only a few somewhat hard-to-get beers, so there's only one relevant question: Are you both happy with the trade? That's the only thing that matters.
You are over $4$ so it's more than fair in term of $ value. However, other than the SARA Cask 200, the other beers are pretty easy to trade for using much easier to get ammo. Prop '13 and Backyard are lesser and lesser in qty nowadays so you'll need more limited beers to pry them out of people's hands. I say this as someone who has all of what you're looking for and definitely won't trade for what you offered up.
