I would consider this a stupid question but do FedEx Office Print & Ship Center ship packages for me also?

I would guess that the FedEx office ship center would ship packages for me hence the name...but I don't want to show up to a FedEx office with a big package (a laptop) and try to ship it to somewhere when they do not handle any kind of shipping....

Also what would be better (cost and time wise) to ship around 15 pound laptop to different state in United States... Fedex or UPS?

I'll look for best answer and choose.

shipping from China to Canada
