Looking for cheap supplies!

Anyone know where to get cheap rock online? Like Seiryu stone or something. I’d also love to find affordable quality plants. I found cheap driftwood on tropicflow if anyone is looking! You don’t know what you’re getting but I like the mystery bags 😏

You know what just tell me any cheap supplies you know of!

Sponge filters, tubing, tanks, substrate, sand, anything! 😁
