Adorama has a $50 off coupon promotion on Ricoh digital cameras including various GXR kits, the PX compact-zoom, the CX5 zoom, and the GRD III. Each camera has a different coupon code which you can see at the aforelinked page. After the coupon code, the prices drop as follows:

+ PX drops to $200 (choice of multiple body colors)
+ CX5 drops to $210
+ GRD III to $450

There is no expiration date mentioned, so the coupons will work until they stop working. Once they stop working, then you will know this promotion has ended.
