Extreme Bartering achievement

[Cogfire]

I tried doing that in the guide, sadly it didn't work. It does the same twice now.

I follow the items in order: Lightbulb, Amber. Strange Journal, Feather, Vial, and finally the Wool.
After I refuse the trader's decision once and then accept the T-shirt and Ink, the achievement still won't pop up.

Is there any mistake to what I did? if so, I'll be very glad to read your reply.

You have to try trading the ink and t-shirt too, and the feather pen after combining it with the ink

Also, the order doesn't matter.

hey it works, I don't even need to combine the ink and feather.
thanks you guys.
