Why does the return shipping fee cost more than my original shipping fee?

Generally, shipping from a residential address to a warehouse costs more than shipping from a warehouse to a residential address. We're able to negotiate bulk shipping rates for outgoing packages due to the high volume of orders we ship everyday. Because our return packages come from a variety of different addresses, those bulk shipping rates are inapplicable to our return labels and the associated return shipping cost is higher. Customers who opt to return their item(s) for a refund to their original form of payment are issued a flat rate for their return shipping label — it is simply a policy our company has put in place to mitigate shipping costs all around, and so as not to absorb shipping costs into the price of our products.
