Walk Behind Lawn Mowers

I purchased the hu800awd in april 2013. I just got the mower registered online with Husqvarna. I got an email back telling me it is registered, but it said my warranty is 2 years. When I bought the mower the warranty said 3 years as well as the huge sticker on the mower. Am I actually getting the full 3 years of warranty? I assume it means I don't have 3 full years of warranty left, so it shows 2years left, but it is actually 2 years and 9 months left. Also I was told when I bought the mower that Husqvarna was sending out a 30 dollar rebate or something that you had to get directly from them. Is this true, and if so how do I acquire this? Thank you for you reply/support.
