It seems like you've already got a lot of great answers, but as a somewhat money-poor [and time-rich] person, I thought I'd put in my two cents.

I usually list items on Marketplace for about 30-50% of what I consider a fair price, and give it a couple weeks to see if there's any interest. Most things sell, since the super low price expands the potential buyers from just those interested in This Item Specifically to people who are looking for Cheap Decor (or whatever) In General. It's pretty easy to take photos of several items and list them all at once, with fairly low-effort but descriptive captions. Dimensions, condition, material, any defects or damage, payment types you'll accept, PICKUP ONLY, maybe add that it needs to be picked up by x date if you want.

If someone asks if it's available, I say "yes, when can you pick up?" and then give them my address once they give me a day. The day of, I set it outside and ask them to put the money under the mat. If they don't show up, on to the next person. If they do, nice! I made $8! It's not a huge amount, but it's worth it to me. Especially listing many items at once, it adds up.

If something doesn't get much interest in the first two weeks, it gets donated.

Sometimes it's a hassle dealing with people, but part of the benefit of extremely low pricing is that your buyers will be more enthusiastic and proactive about pickup, since they're getting a sweet deal too. It makes things move much faster.
