If you have a Habitat for Humanity organization in your area, they usually also have a retail outlet known as a ReStore where you can buy slightly used material for your remodeling jobs. I always check my local restore first. Just this week I got two remnant pieces of counter top (one 30” the other 15”) for less than $10. They also sell 4×4 inch wall tile for about .10ยข each. They carry just about anything you could possibly need, and buying it there keeps the stuff out of the landfill. The money also goes to a good cause.
We are going there tomorrow to pick up some supplies for our bathroom/kitchen/living room remodel. We should probably take both trucks, as I know we are going to find all sorts of good deals.
Give it a shot, hopefully you can find something similar in your area.
