I have been buying from Newegg for years - and occasionally they will have a paypal promotion discount - but that is usually around the holidays-
Your best bet is to go to their site every day - preferably in the morning and look at their sales - especially the Daily "Shocker" which has some kickazz deals - subscribe to their emailings and again they come up with really good prices and usually free shipping-
Newegg has become a favorite shopping place with most American cdfreaks in the lower 48-
Suggestion - ALWAYS double check their prices using google - I have found a number of items that Amazon beats them - sometimes by a wide margin-eh!!
