Best Buy also carries these. Might want to try to lower the price by either buying and returning for a price match later, to get an extra 10% off, or by price matching immediately and also using the 12% off coupon for rewards members. No guarantee that they'll do a PM and allow the use of a coupon at the same time, but you can always try.

You can also get a PM at OfficeMax or Office Depot. Don't forget to bring the Circuit City ad with you.
