The shipping cost is determined by actual shipping weight and zip code/location. In order to get a shipping cost for your order, you will need to put the items in the cart and sign-in with your zip code. Once you are signed in with your zip code, there will be a pull down menu with shipping options and prices for you to compare. We have included a chart for approximate shipping charges using USPS Priority mail. You can use this chart to estimate your shipping cost. As mentioned before, the actual cost will be determined by the shipping weight and zip code combination. There are some cases, based on product size, where we can ship with a flat rate priority box which could reduce the shipping cost to the east coast, Alaska, or Hawaii. We will always try to choose the lowest cost shipping option if possible. In those cases, we will reduce the shipping cost and email you to notify you of the change. In addition, items that weigh less than 15 pounds but measure more than 84 inches in combined length and distance around the thickest part must pay the 15-pound Priority Mail zoned rate.
