To offer customers savings on shipping, we offer discounts when shipping multiple items from our store. We cannot issue refunds on shipping once an order is finalized so please follow the 5 steps below and ask if you are having trouble with the discount before you make a purchase.

  1. Be sure you are using the US site: www.ebay.com
  2. Select Add to Cart (instead of Buy It Now) with items from our store 365Cycles
  3. Click on Proceed to Checkout. On the checkout page, the shipping service on each line item needs to match
  4. Compare First Class vs Priority as sometimes Priority can be cheaper and it gets to you faster!
  5. You’ll need to change the shipping method to Priority on every item in your cart before the rate can be calculated.
