Start a contest and send gifts to winners

Sorry if my question sounds too dumb but I never did it before. so ok you can make fun of me but post useful answer as well

I have few membership sites and Im thinking to start some contests with real prizes like camera , laptop, ps3 etc. Is there any site where I can pay with my paypal or my credit card or bank account and they will ship it to the winner ? Is kinda difficult to order the gifts , receive them at my house and ship them again to winners..

Last time , years ago when I tried that some companies refused saying they are afraid to take my payment as I may be paying with a stolen card , they wanted to ship only to the address filled on card.

Why not use Amazon? You can ship purchase to anybody you want, and shipping is often free.

Oh forgot to add .. Is there any service that will write my company name on the package or a custom printed letter in the package?
