When do the preseason mags come out?

I wanna get my hands on a Lindy’s, Street & Smith’s, Athlon, ect.
When do those usually come out? I was thinking August, but that does seem a little bit early. Maybe mid September?

I use to get Street and Smith every year and it would come out around mid-Sept/first of Oct.(and I believe it was the 1st one to came out each year). Check in the Football Street and Smith for the date because they use to list the est. date that the upcoming preview mag. would be out.

thanks pcon, that sounds about right
