What is MAP Pricing?

MAP stands for Minimum Advertised Price. It's a policy set by manufacturers that limits how low retailers can advertise their prices.

The good news? We can often sell below MAP - we just can't show that price publicly. When you request a price by email or add to cart, you'll see our actual (often lower) price.

This isn't a trick - it's how we stay compliant while still offering you the best deals possible.
