This was posted a long time ago but it hasn't changed much. Let's say I have a rainbow potion. I'd be happy to trade that for some wood on that day, so in the box for what I'm offering I type 'rainbow' and then the trades are something like
1 ruby for 15 Rainbow Potions
(Actually good item) 30 Rainbow Potions
When I'd expect to see something like:
50 Wood for 1 Rainbow Potion
100 Wood for 1 Rainbow Potion, etc.
But it's like that for EVERY item pretty much and the trades never go away so it's completely filled with really silly trade options. However once in a while I'll see schematics I need for modest amounts of vermillion and I always hit 'accept' so fast. ^_^
