When a trade involves a growler(s), do you factor in the cost of the growler in the value of the trade? This came to mind after picking up a few $15 1Ls from Society Cheers,
All my trades involving growlers include the cost of growlers since I usually trade in combination (both growlers and bottles or I get bottles and ship out growlers). I can see if trades involve only growlers for equal numbers (i.e 2x 1/2 growlers for 2x 1/2 growlers), then you can agree to offset that cost.
I often trade HF growlers and I always include the cost of the glass in the $4$ value. I also break down the cost of the beer and the glass so there is no confusion for the person I'm trading with. The only times I have not included the cost of the growlers is when they were sending empty HF growlers in return.
