Please Note: Updated Monday, May 30, 2020  We are open for business as usual. Well, mostly usual. We hold and ship inventory locally as well as directly from manufacturers and from some marine distributors. We are doing our best to reflect inventory that is actually available, but inventory updates are slower than usual due to the changing work situations for all business. Additionally, we now have started to see longer than normal backorders from manufacturers. We recommend that if you need a product not to wait until the last minute to order, as inventory may be gone for a substantial period of time once they go on backorder. International orders may also take longer than normal to ship. We are sorry for these delays.
