I used to really do well on FB marketplace, but it seems it’s stalled. Selling baby/children’s clothes deeply discounted, toys, purses, household items and furniture.
For smaller items that are easy to ship I use fb with shipping or mercari. I like varagesale for buying, but not so much selling (I’m outside of the direct area, so to make a sale I need to drive 40 minutes away which isn’t worth it for a $5-10 sale)
