These deals have expired. Tamron announced new rebates effective September 1 – October 31, 2015
Here are the current Tamron Mail-in Rebates valid through August 31, 2015. I’m not normally a fan of mail-in rebates, but Tamron is prompt is sending their rebates and I very rarely see any issues with their rebate program. You can save between $30 and $100 on select lenses.
