Ocean: No prob. H/w, if its for the Leapfrog books then do let me know soon, coz I don't want to keep the other mummy waiting. As for paying with your credit card or my IL's, if its a consolidated order, then I think better if my IL pays for it using her credit card, esp if its from Leapfrog. This is because the last time we ordered from Leapfrog, they really messed up our orders, and my IL had to return and exchange some of the goods. If this happens again, and its not her credit card that is being used, then she won't be able to correct the mistake easily.
For sellers like Amazon.com, I'm fairly confident they won't mess up the orders, so it would be good for individual buyers to pay for their own purchases, as there would be a lot less money passing around.
