Tamron has updated their lens mail-in rebates for September and October, 2015. They increased the rebate amount on a few lenses and added the 28-300mm lens as well. Tamron does a good job with their mail-in rebates with a quick turn around and very little hassle in my experience. Purchasing a Tamron lens using the links to Amazon helps to support this site.
