Update:
I am still buying all lvl 40 items for 1fg I will pay 2 fg for +4 or better. Not paying anymore. My reasoning is simple. The chances of getting rare or better are just too low. Factor in the random 1006 disconnects which ironically seem to happen more often when doing Legendary or better mutes. Its not worth it IMO. I am also cheap and poor but that's my problem

I think
might pay more for +2 or better 40's but I think his focus is on higher lvl mutes. Maybe he will buy if you put up for more than 2fg. I will check daily and keep buying the 40's daily that are within my budget.
During faster muting events and when I have tons of space I will clear the mp of all 35's. I will consider 2fg on mutes +5 or better on 35's.
I wish I had more fg and could pay more for mutes but these are the restrictions that I have to manage.
Thanks for everything HC Community,
