Just wanted to share this very recent experience with an Amazon purchase:
2/24/07 - Placed an order for TurboCADv12, price: $79.99 (free shipping).2/27/07 05:30 - Noticed price dropped to $73.99 (still free shipping).
2/27/07 05:31 - sent an email to CS via the "Contact Us" link on their website politely suggesting they credit me the difference.2/27/07 13:11 - received and email from Amazon CS stating "The discounts we offer for items on our web site do vary from time to time. I've checked your order, and found that we recently offered a greater discount on item " TurboCAD Deluxe v12 " than at the time you placed your order. Since this item was shipped so recently, I have requested a refund of $6.00 to your credit card. This amount reflects the difference between the price you were charged and the discounted price. The refund should be processed in the next few days and will appear as a credit on your next billing statement.
Say what you will about Amazon's funky price excursions--this, to me is good CS.
No affiliation w/ Amazon, just pleased something went my way for a change.
