Here are a few good posts from the Carnival of Personal Finance #95:
The Finance Buff has an interesting article about Who Pays for Credit Card Rewards. My answer: it's a combination of credit card customers who carry a balance, and the business at which you made the purchase. I disagree that businesses raise their prices to compensate for credit card fees - other forms of payment also carry a cost. Cash means going to the bank and handling large quantities of change (both of which cost money). Checks carry a risk of non-payment, and so forth. The rewards you receive from the credit card companies are a portion of the efficiencies created by the use of credit cards compared to these alternate methods of payment, as well as a "fine" paid by consumers who carry a balance.
Plonkee Money thinks that atheists should tithe, or more specifically that non-religious folks who consider themselves humanists have an obligation to try to make this world a better place by helping the less fortunate. As someone who considers himself a humanist, I completely agree.
Tight Fisted Miser is debating The Economics of Sunk Costs as they relate to his finishing his law degree. Stick with it buddy! Even a lawyer can has hope of redemption. I can personally testify to that fact... :-)
Finally, The Frugal Law Student lists 5 Things You Should Never Buy New. One of these things is books. Man, do I disagree. There is nothing greater than the smell of a brand new, unwrinkled book and money be damned!
