i know...at one time, we had (here at least), UPS, FedEx, RPS, USPS, USPS, USPS Parcel, and DHL
well DHL (i worked for them as well) is only from airport to sorting center, to delivery for international shipments only now.
and pick up back to sorting center for overseas shipments. however, i get some of my meds, picked up by DHL, and they then turn that over to USPS. otherwise, they cannot pickup/deliver to the customers.
USPS Parcel was done away with in cost cutting measures, for the letter carriers to deliver.
RPS (i worked for them) got bought out by FedEx, and turned into FedEx Ground
when we had shipping choices, the prices were competitive.
now, if only 1 shipper? not only do we lose in choices, we lose in higher shipping prices, as it's a lock-in for the seller of the products.
this is why i LOVE Amazon Prime,,,FREE same day, or next day, or 3 days tops shipping. 7 days a week.
