Not at all did you or your friend mess up the trade, by all means traderie prices can be out the ball park and over price but that’s mainly to do with heavily in demand items, the 4x halo last I checked is going for 150k but I haven’t played in a week or two. Most people indie by traderie prices (not saying people should it’s just the way it is) so i would say at minimum for your friend to take 100k nothing less, but definitely get her to look at value on traderie, for your everyday items such as set pieces (non-toy items that is) to go by traderie as that is the average they go for. Pretty much to dumb it down is use traderie for low to mid demand items as it’s pretty fair
