Trade-In promotion for Sony RX100 and RX10

Amazon is running a Trade-In Promotion for the Sony RX10 and RX100* digital cameras. You trade-in a qualifying camera or camcorder or smartphone. Three business days later, you will receive an email with a promotional code for either $50 off the RX100* cameras or $100 off the RX10 camera. One trade-in promo code per order. Only new condition RX10/RX100* cameras sold by Amazon herself are eligible (not 3rd-party sellers, not used/refurbs). This promotion ends 3/28/15. More details over there.

UPDATE #1: Adorama has a Sony RX Trade-In promotion as well.

UPDATE #2: B&H Photo has a Sony RX trade-in promotion as well.
