Buying used diy wedding decor

I found local buy/sell wedding groups on facebook for my area. I bought a handful of items on there. For my SILs wedding, we're going to thrift stores for some stuff for her shower, so those and garage sales may also be an option

Hobby lobby also has a lot of wedding decors at a good prices. Maybe you can check their website to see if you find any there. Do you also need any .svg or vinyl decals? You can also just order the vinyl decals and stick it on your décor to make it customized. Let me know if you want some custom vinyl decals, I also making some for myself and my friends too

Have you tried thrift stores like the Salvation Army or Loaves and Fishes, Hope Mission Stores? Usually these charity stores will have good products with some of the best prices that can't be beat, and some really unique stuff that makes it so easy to be creative for your wedding.
