Newegg.com is offering new customers (register for a new account) $10 off their first $50 purchase.  See site for complete info/exclusions.  Use promo code: NEWCUSTOMER10.  Good thru May 31, 2011.  I've enjoyed purchasing a bunch of stuff from them over the years.  Great offers and customer service.  More info about Newegg.com can be found here.
