We listened to customer feedback which suggested lowering pricing meaningfully to support the shopping experience and encourage new customers. We are excited to announce significant price reductions across many of our products—up to 50% off. Our goal is to provide you with better overall value while continuing to offer the quality and service you expect from us.

To support the new lower pricing, free shipping will only be available on orders of $125.00 USD or more*. Orders below this amount will have standard shipping rates based on your chosen shipping method at checkout.
