I am aware that Paypal offers some fields in your seller profile for entering the weight and price for shipping costs and I notice that when you have it turned on and make a test order it makes you enter your zip code and then appears to give you a price based on that. But I don't see anywhere that it says whether this is UPS, FEDEX, or USPS.... is it universal?
We want to use Paypal to take payments on our website and we also need to have shipping calculation in real-time and to be paid with their transaction. But we prefer to use Fedex. Will the paypal shipping calculations be accurate for Fedex, or what carrier do they use to base their calculations on?
Thanks for your help.
