Bill Me Later has horrible customer relations and questionable business practices. I made a charge through Continental Airlines in March. The charge didn't even appear on my Bill Me Later account until June, and after 2 other charges I made in April had posted. I had paid my account in full in May - but since they never even posted my March charge until June, I didn't see it. Luckily I caught it in July, after they charged me a finance fee. So, it's only $10 - but when I called they were horrible. They blamed Continental and me, and told me I had to fax them a dispute form and evidence. Of course, they do that so I'll just get ticked off and pay the $10... well it worked, but I'm also going everywhere I can to warn you!
STAY AWAY FROM BILL ME LATER - they're horrible!
