I purchase a lot of stuff online. I also sell off stuff I am not using any more to fund purchases. My first preference for a carrier is FedEx because they are very gentle with packages. In contrast, boxes that come by UPS or USPS look like they have been dropped, had larger and heavier boxes stacked on top of them., or otherwise mangled. On top of that, FedEx is usually much cheaper than either UPS or USPS. The only time I use USPS is when I can use the flat rate boxes or envelopes.
