I currently have a 5 year 75k esp plan and was wondering if anyone knew if they could be extended or does another whole plan have to be purchased i couldnt find any info about it anywere also were online is a good place to purchase one

 

I believe I asked that question when I bought mine and you could as long as you were still in warranty. You'd have to pay the price delta of what you paid vs what the new (extended) plan price was at the time you wanted to change it. Don't quote me on this as I could very well be wrong. I purchased the 8/150, so can't really extend mine anyhow.
