New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
