I haven't been making as big an effort as I probably should be trying to sell things as I declutter. I just don't have the patience to store things for long while I wait for them to sell. Once I decide to get rid of something, I just want it gone. Occasionally, I make an exception and it pays off.
Thankfully, this only took a couple days to sell on Amazon. This is one of the cookbooks I had in both paper and digital formats.
Total cash from decluttering so far this year: $545
