As some of you have already heard, we will be closing the doors to Con-Mat Supply this spring. This was not an easy decision but one that I feel was right for myself and family. I want to thank everyone who has done business with us over the years.

With that being said, I will be liquidating my inventory over the next few weeks at a 30% discount. Please feel free to reach out to me directly if you have any questions. 406-939-4575

Sincerely,
Grant Aldinger
