the only way to get any trimmed armour in runescape w/o paying coins is by treasure trails.
you can only do these if your a member:)
i don't know why youd want adday trim instead of rune but ok id say for free the one way i can think of is party room if someone drops it in party room and your lucky enough to pop the ballon with it...
il give u it free? email me at (themasterfulcow@aol.com) if u want it
Real world trading can get you banned.
NO
Only if your a member can you and you get from clue scrools lvl 2.
