Johnstone Supply regularly receives price increases from our manufacturers to certain products and/or product families. In an effort to communicate these manufacturer price increases to our customers, we publish them here in advance of their effective dates. Recently we have been experiencing a very volatile price environment as tariffs are being imposed on imports so prices may change without notice.

Below are the details of our recent and upcoming manufacturer price increases:
