Where to find plastic lumber?

Does anyone know of a local lumber yard that sells (or could order) plastic lumber?

I’m looking for 2x10s and 4x4s. Found some at Menards but they can only be ordered in quantities of 15 (I need 18) and Lowes price was more than double Menards. :grimacing:

When I rebuilt my deck a few years ago, I got mine at MPC Cashway in Lansing, by the airport. I think I remember Carter Lumber off Old 27 north of town, and Gilbert off Penn having some too.

Thanks, I’ll look them up. I am looking for rough lumber sizes and not decking (2x8x10s specifically) but we’ll see!
