Yeah the annoyingly high prices blew my mind at first.
Fun thing is when I compare the stuff now almost all of it looks like unnecessary junk to me.
At least what they sell in the Grove before lvl.4 ( or whatever influences the merchants inventory ).
I sell them the trash of almost everything I find during our groups travel - and then I can easily afford one or two items I might want later on.
But ultimately buying in Act 1 feels like a trap.
They can take my trash. But I won't take theirs, especially not if its that overprized.
The nerf the Tiefling and Druid merchant has.
We are probably their only bet of SURVIVAL.
But sure sell us your stuff with a scent of weave (green quality) about them, sell it to a prize comparable to extortion.
When I joined the Goblins once to raid the Grove, I was actually only focussed on getting back at the Merchants.
