I'm trying to redirect the drainage from my downspouts around my house and I've read that 3-inch corrugated pipe is a better option since it's easier to bury compared to 4-inch. I checked Home Depot and they have lots of fittings for 3-inch pipes, but they don't have the actual pipe in stock. I've also looked around at local hardware stores, and none of them have it available for ordering either. Is there some supply issue going on, or are a lot of people just working on landscaping projects in my area?

I'd second the recommendation for 4-inch if you can manage it. The 3-inch stuff has a lot of drawbacks—getting rid of bellies can be a pain, and roots can invade pretty easily. It might be a bit more work upfront, but it'll likely save you from trouble down the line. Plus, yes, it seems like a lot of folks are ramping up landscaping projects recently, which might be affecting availability!
Honestly, you might want to consider going with a 4-inch pipe if you have the space for it. Digging a little deeper is usually worth it in the long run. The standard 3-inch corrugated pipes can be pretty flimsy and prone to issues like dips or leaks over time. Plus, they tend to break easily, which can lead to more headaches later. If you're near any irrigation or landscape supply stores, they often have a better selection than typical hardware stores!
