Pay Pal sucks

i hate pay pal. i bought a new nalgene on ebay and i can't figure out how to pay for it using my pay pal. i have bought a few things on ebay before so this is not my first time. why is this so difficult? the ebay web site www.ebay.com is very difficult to navagate through when you are trying to pay. maybe it's just for me. but i can't figure out how to may for my nalgene. everytime i click on pay now. it takes me to the paypal and i do it but then it keeps sending me to the same sites over and over. i thought i was more computer knowledgable than this... obviously not.
