The easiest way to reduce shipping costs is by reducing or optimizing packaging.  Depending on the size of the product there are different ways to optimize shipping, but in essence the smaller and lighter the package is the less shipping will cost.  Every ounce matters so reducing packaging or using light weight packaging will have a huge effect in reducing shipping costs.  There are risk involved.  If less or lighter packaging is used this will reduce the integrity of the package and could risk breaking products which will cause losses in product and additional costs to re-ship, as well as an unhappy customer.  Packaging is important for your brand and the customer experience, so it is also important to weigh the aesthetics of the package in addition to the weight and size. It is best to test different packaging types to find a balance of the best packaging to use which will also reduce your shipping rates.  If we are provided samples or even descriptions of the products we would be happy to provide suggestions.
