Although, I haven't really had any personal experience to share about them. Shipwire seems like a legit business and they are pretty straight forward with the fees you need to pay. They're a company that basically provides a warehouse for your products plus do everything there is to do to ship your products to your customers. If you're not to sure about them, might I suggest you give their free trial a try. Just to get a feel of how it works and see if it's what you need for your business.
Is there anybody currently using shipwire or has used shipwire in the past? Kindly lend us a hand by sharing your experience and feedback about this company. Thanks in advance! :)
