I got this in email from CameraLand :
If you buy a new EL 42mm or 50mm Swarovision or a new SLC 8x42 HD or SLC 10x42 HD you can trade in your old EL 8.5x42, 10x42 EL or SLC 10x42 (Only the dark Green version with a serial #D7450 or more current).
The way this will work is you buy your new binocular from us and then contact Swarovski for an RA# and send your binocular in to them. Your binocular must be functional.
They will allow $700.00 for a 10x42 SLC-neu, $850.00 for an 8.5x42 EL, and $900.00 for a 10x42 EL. Swarovski will then send you a payment.
I thought I pass the info along for the Swarowski guys .......
