Yes, they are contracted with The UPS Store (Not UPS - dont ask me what the difference is). You can literally just drop equipment off there at no charge. Super quick.
Usually you can call them and get the information to mail it in but be careful. I mailed in a router once and never got the credit for it, they claimed they never got it.
You can via UPS or FedEx. Details can be found on their website.
