Stardust Companies is a group of organizations based in Scottsdale, Arizona, whose mission is: "to be a catalyst for building stable neighborhoods, through active involvement and engagement in our community." [From their web site.] This place is an awesome trip west to either DONATE your old building materials, doors, cabinets, sinks, etc., or to find an amazing bargain by shopping there. I have been there many many times and the inventory is constantly changing. You might find an entire suite of beautiful kitchen cabinets - maybe 2 years old - ripped out of a Paradise Valley home because the owners want something new. A large lot of brand new tile because they ordered too much for the job. A huge selection of solid wood beautiful doors. Vintage sinks and toilets (okay, a little bit of ew there sometimes)... it's a big hot warehouse but many contractors make it a habit to take their job site's discards to Stardust so you can find some really awesome deals here. It's a 501c3 non profit so you can take a tax deduction if you make a donation; and your purchases help the non-profit with its mission as stated above. So go, you'll dig it.
