11.16.23 - 2024 Shipping Changes

Rock River Laboratory will no longer offer free shipping, effective January 1st, 2024 because of the constant rise in shipping costs and poor carrier customer service. Moving forward, a ‘chargeback’ system for customer shipments will be enacted. Customers who continue to use our shipping labels will leverage our negotiated, reduced rates with carriers. Ordering labels will now require login with your existing Rock River Laboratory credentials. Flat-rate charges will only occur after a shipment arrives at our lab. See the 2024 shipping rates and more details about this change here. Or contact our customer service team with any questions:
