Yes it sounds pretty good
I don't really know too much about it... That's the basics of how it works. You'll have to read up on the Paypal website if you want more information on it.
Although you should know that there is almost always a minimum amount before you can use Paypal Credit. Some sites have this as low as $50, others up to almost $200. On Amazon, it's up to the individual seller to decide whether to accept this type of payment and to set a minimum amount. I believe the minimum on Newegg is $50 in your cart.
