Try Buy.com and use Google Checkout ("GCO") to get $20 off of $50. Buy.com has the James Bond Ultimate Collection - Volume 2 with free shipping. Right now you could get the JB Vol 2 collection for $46.99 using GCO - if you do not pay sales tax on your Buy.com purchases. Buy.com charges sales tax if your order is shipped to California, Maryland, Massachusetts, or Tennessee. Also, if sales tax applies, it is calculated on the total price - before the $20 off of $50 GCO discount.
The next cheapest price I've seen for JB Vol 2 is $55 at DeepDiscountDVD.com.
I just had another thought - James Bond Volumes 3 and 4 will be released next Tuesday (12-12-2005). Some of the B&M's (or even e-tailers) may have some promotional discount on Volumes 1 & 2 to go along with these new releases. If there is going to be any type of promotional discount like this at the B&M's next week, I'm sure that we'll find out about it in next week's Weekly RoundUp.
