A lot of posts on the Personal Finance blogs have outlined the hows, whys and wherefores of doing a 0% balance transfer Arbitrage to earn interest on OPM. Lots of other blogs deal with those struggling to pay off CC debt, and who could benefit from transferring their current balance to a lower rate CC. But how do you find the best CC available?
I've just had a look at a site which lets you compare the various features of Credit Cards - it even has a page listing cards that have a 0% balance transfer available! All in all this looks like a very useful site for my US readers.
