256MB of Crucial PC2100 is down to $47 on Newegg, that's $6 less than from Crucial! (From Crucial, it's $70.99, with 10% off it's $63.89, minus a $15 coupon, which is $52.92!)
Of course, Fedex 2nd day shipping is free from Crucial, but it's $6 from Newegg. But if you've got a HDD or a case or something you want to order from Newegg, it'll absorb alot of the shipping for the RAM, so it will be cheaper from newegg.
