Discounts for Christmas on Ipod Touch?
I recommend heading on over to AppleInsider.  They keep some really neat matrices of all the major Apple products and their prices at various online retailers.

For example, the pricing matrix for the iPod touch shows this for 2 Dec 2011:



The best price is bolded.  It looks like you can get anywhere between 5 and 10% off an iPod touch, depending on which store you buy it from.  I'll also throw out there that if you have a friend who works for Apple, you might want to talk to him/her to see if they could help you get a discount as well.
