I probably have but I couldn't swear to it. I have received a pretty good stack of calendars and whatnot from various sportsbooks recently but I haven't bothered to check who exactly sent what.
Most of it goes straight to recycling. What they should do if they want my attention is send a nice kitten calendar. I like a nice kitten calendar.
It's funny, I have mine posted in my home office, and every time I fill appointments and get to the end and flip and see there is not another month, I get the new one. lol. Every August.
