I've been selling on eBay recently & I often receive questions if I will ship internationally. I'm in the US so I only ship domestic. I've even turned down people in Canada because it seems so overwhelming to me - the shipping process that is. Am I missing out on something here by not shipping int'l? I've been reading some threads about people claiming they never receive items, custom charges, sellers waiting months for the "unclaimed" parcels to return. Am I shutting myself off from potential buyers or saving myself from more work? Is the USPS better than FedEx or DHL?
