Buy/Sell/Trade Forum

I'm interested in selling off most if not all of my cards in order to free up some living space.  I've received a bunch of onsie/twosie requests for trading and the effort just isn't worth it.  (Nothing personal to anyone, just honesty.)

Is there a method in the "set for sale" option of the website to let folks know that I'm open to selling cards as a collection - basically selling an entire binder that consists of whatever I may have for sport/year/manufacturer/series?  I wasn't seeing a way to do that.

Also, what do y'all do with stacks of spare, minimal-value cards these days?  I searched the forum and saw where a non-profit had been accepting them as gifts for children in hospitals, but that's been shut down due to overwhelming volume.

I would create a posting in the buy/sell/trade section listing sets and asking price.
