You're welcome to cancel your subscription at any time. However, if you cancel before you receive your second shipment, we are required to charge a price adjustment fee of the difference you would have paid for a one time purchase. This prevents people from signing up to get the discount for a one time purchase and rewards those who stick to their 310 healthy habits. For example, if you ordered a 310 Shake at $51.00 with Subscribe & Save, but cancel before your second shipment, you will be charged $17 to the card you have on file, the remainder of what the one-time price of $68.00 would be. But not to worry, there are no extra charges for skipping or postponing shipments or for changing the product you receive.
