I got mine weeks ago, but then again I bought the shells the first day of the program and sent everything in about a day or two later. I cut them off of every box like they said to do to avoid any problems since it appears as if this is handled by an outside company and not Winchester themselves.
Just a little tip if you want to save the boxes; you can take an exact knife and score around the UPC and peel it off. After a few boxes it gets quick. I sent mine in early June, the site says they were accepted, just waiting like a good farmer.
