Hi Bryce,
Developing a worldwide market is one of the key advantages of dropshipping. Instead of wholesale, where you will get a much better price of course, you also have double shipping costs to consider. The initial cost of shipping the load to your distribution point, then of course breaking the load down, repackaging and shipping to your retail buyer at the point of sale.
Dropshipping allows you to have the products sent directly to the retail customer from the supplier themselves, nothing has to come to you first, so no double handling involved. Your customer base is only limited by your shipper's shipping, so if a dropshipper offers worldwide shipping, then you have the potential of selling the products worldwide through the various avenues open to you.
Cheers
