S&W had a Spring Rebate on some Models, it ended Apr. 30.
You can still send in your photo of the QR Code on the Box and a photo of LGS Bill of Sale, that deadline is May 30th.
The Rebate is $50 on my new J-frame, I emailed mine in on the 23rd it was approved, and I got the VISA Gift debit card in the mail on the 30th.
