With my 70-200mm F4 IS , I also got a discount voucher from digitalrev. You cannot use it at ebay, only their website www.digitalrev.com
. Also this is only for a UK buyer. I've been given one and I don't have any money to buy anything more yet, so whoever wants it let me know. There is only one so first come, first served. The expiry date is 31st of March this year. Please only PM me if you definately going to buy something because I'd rather give it to someone who is actually going to use it.
