Down to $4.98 now, still high but not as high as earlier in the year. I don't really remember what they were pre covid, like 2 something I think.
Plywood still seems very expensive though, I was not tracking it as much but I know it hit close to $100 for a 3/4" board at one point. Still around $82 for that. 1/2" which is more typical to buy is $56. I'm pretty sure that was more like $20 something before.
Lot of people on FB selling rough cut lumber that they've milled themselves, so right now it still makes more sense to buy from those people. If you need sheets it's best to just rethick how you build and use planks. Install them at an angle so you give the structure more rigidity. If you want to go all out pass them through the table saw to create a tongue and grove so you don't have cracks between.
I'm thinking of starting on my water tower and outhouse this year at my homestead property, just something crude and probably temporary so don't want to put much money into it. I'm not setup to mill my own lumber yet but I will probably just use logs. When using non engineered lumber just overbuild everything and it's still cheaper.
