Simply the worst shipping company ever existed. My parcels haven't moved for more than 2 weeks. And some remains at the initial stage i.e. "En route to DHL eCommerce distribution center or awaiting processing Melrose Park, IL, US" since August 15, 2025. It took 7 days for a parcel to move from Whittier, CA, US to "Arrival in country [transit country] UNITED STATES". There has been no update since then. Some of my shipments have more than one tracking number. Very confusing. This is not the kind of service that I expect after paying $12 for shipping fees (more expensive than the price of the book itself). Should have bought books from other online bookstore instead which charges similar shipping fees, but ships using a much reliable shipping company.
