What do you do when you can't find anything to add?

I typically work on one of my side projects I have going on when I hit a dry spell. They are typically less expensive items that I really don’t actively search.
Here’s the issue I have had and continue to have with doing this (this is probably just me so you’ll probably be fine). While the side project is less expensive items I start to purchase these type items and continue to purchase and then don’t have enough money when an item I really like more comes available.
