i've had lots of hits and misses lately. not to long ago i got a item worth 40k in the mp. then like 3 days later another item worth around 15k. i usually stock up on stuff then dump it in there 98% of the fish and other aquarium stuff i drop in cuz i don't use that feature. so once a week i go through my invo and it gets dumped.
I always donate items on my monthly inventory cleaning.
Not crappy stuff though, like things someone would want but aren't worth the effort to sell.
I've never really dived myself though... Maybe once when the feature came out
