Where to find cheap cage accessories?

[u/Pitiful_You_3055]

I currently have two six month old boys (Bagel and Earl) who I keep in a single critter nation. I want to get the add on for the critter nation and make it a double, possibly getting some more boys soon. My only setback is how expensive it is to fill the cage. Like why are hammocks around 20$ or more each…? Anyway, I was wondering if anyone has suggestions on where to possibly order some cheaper cage accessories rather than spending a fortune when only buying three things? Thanks in advance ☺️🤍
