Great Service

I ordered a variety of hardware for a deck I'm building. I received my first order and it only had a box of screws. I called customer service and they explained the rest of the order is coming from a different delivery service. They were very nice and professional. The cost of the hardware was almost half the price of the big box stores and the same brands.

Thank you for letting us know how we did. I am sorry we didn't get the tracking information to you so that you knew to expect multiple packages. I will check in to that further. Thank you for your understanding, we appreciate it! Thanks, Tammy ~ Fasteners Plus Team
