Watch out - this place has turned into a ripoff! I was told a specific used cabinet cost $150 when the same NEW cabinet could be bought at Home Depot for $100. I pointed this out. Employee didnt care. Waste of time.

WATCH YOURSELF! They quoted me "$2 to $3.50" per linear foot for composite deck board. Lowe's sells it for $2 plf NEW. Do your homework, these guys seem eager to rip people off!

Service sucks, most items don't have prices, and prices can go wild, depending on the day. There are some bargains, and they do have a large variety of items, but watch out for those prices. Again, they do have some items at great prices, but others a lot more expensive than box stores.

Awesome place and high quality materials at great prices, I noticed a lot of people don't like the organization system but as far as surplus stores go I think it is very well done. Be prepared to spend some time because there is a lot to go through and is not a home depo type store.

I'd called all over town looking for something with no luck. Called here, talked to Armando. I mentioned that if they had what I needed, it was going to take me 1+ hour to get there. He was willing to go check for me that they had what I needed. They did! The store was hopping when I got there, so I was glad I'd caught him the day before when he wasn't super busy. While I was there several people helped me navigate to exactly where I needed to get my product (it's huge, I saw many thin that will be useful, and I got turned around). Customer service was terrific, starting with Armando and all the way through! The price I was also great! I'll definitely be back.
