Due to developments with international tariffs, unfortunately we can no longer guarantee prices for extended periods of time. Prices shown on our website can now be only general pricing and all projects will need to be quoted for exact pricing. Quotes will be honored for specified time period, and if not specified will be subject to change up to the day we confirm the order with you. Once your order is confirmed, product pricing is firm. We sincerely regret this aspect to pricing, but price changes due to tariffs are beyond our immediate control. We can only offer to be in communication with you as soon as we know of changes that affect your quoted project. As always, unless there is a firm quote for shipping, those charges are also quoted as in effect at the time of the quote, and will be re-quoted on confirmation if required. Shipping charges are set by the shipping services such as UPS and FedEx, and are out of our direct control. Thank you for your understanding.
