I just checked out Accessgroup.org and northstar.org trying to compare their Stafford Loan offers. All offer the fixed rate, 6.8% Stafford as set by the gov't, but then in addition each offer these extras:

Access Group offers 1 interest rate point deduction (starting at beginning of repayment period) plus if you have automatic withdraw and if you pay on time for 4 years, your rate will then drop to 3.8%.

Northstar (T.H.E. Loans) says that after the 2nd month of repayment they will give you 1.3% of your loan principal back, applied to the interest on your loan. This rate is annualized, so if you have $55,500 in loans at the end of law school, after 2 payments you'll start getting $60.13/mo taken off your total interest amount. (I figured 55,500 x 1.3% = 721.5; 721.5/12=60.125)

Now, I have no idea which of these offers is cheaper in the long run, assuming you have the loan payment directly withdrawn from your checking account every month and never miss a payment. Any math whiz want to advise? TIA!
