Hello my friends! Today I am looking for three different things

First I am looking for any and all fics where the boys get involved with law enforcement. I would prefer ones with castiel and/or Crowley but all are fine. Crossovers are great and please no wincest.

Second I was wondering if there were any fics of sam finding out about dean and cas's relationship.
Or also where dean and cas's get confronted or talked to by a homofobe and cas reveals he is an angel. Basically just any destiel you can find.

And third I was wondering if there were any fics of the boys or team free will going on a shopping trip. I once read one like this that was an outside pov and it was amazing so now 8 was just wondering if there were any more like it.
P.S.
The grocery shopping fic is called the snow people of Walmart:
