COVID-19 Alert To DIYers: COVID-19 has severely affected supplier inventory. Product availability, at the moment, is in flux. If you order today, depending on the product, there may be a significant delay in shipping it to you. We apologize for any delays, and assure you that products will be shipped as soon as we can get them. Before COVID, we had significant stock of nearly every popular product that we sell. But demand has outpaced our supplier's ability to meet it, and has exhausted the stock we had purchased to meet increased demand during the government-mandated lockdowns. If you need the product right away, it is unlikely we will be able to accommodate you. For that we apologize. We ask for your patience as we all navigate this unique situation together. Be nice to our employees, they are doing their best to answer your questions and get your product to you as quickly as they can.
Regarding Shipping: Like our suppliers, shipping companies have been deeply affected by the COVID-19 epidemic. Please understand, at the moment, shipping speeds are varying from their promised times. While we ship most items promptly, UPS and USPS, are often not getting products to our customers within the promised timeframe. We are unable to offer refunds for slower shipping at the moment, as this is not within our control. We pay for the shipping speed requested, and, at the moment, our shipping partners are unable to meet their own standards of speed and reliability (this is true of overnight as well) We apologize for this, but can't do anything about it. Please be aware, however, that shipping speeds still matter. While 3-day shipping may, sometimes mean 4-day shipping, it will still be faster than Ground. If you need your product quickly, please choose faster shipping, as it will be faster. But do not expect to get the product in the expected timeframe.
To installers: We have seen an uptick in orders from individuals we suspect to be professional installers. If you are here to get product quickly because you are unable to get the product at your usual supplier, rest assured, we are also out of the product and won't be able to fulfill your order in a timely manner. Like our end-users, we will be delivering products as soon as we get them in.
