I know, Amazon's really good in my experience to list the sizes of stuff on their site. In fact, when looking at the cal's on B&N, I tried opening up a window to Amazon & looking for the B&N cal I was interested in on Amazon so I could get the size but Amazon doesn't carry any of the B&N cals I'm interested in. Heck, I also tried going to the cal's publisher's sites and either the pub only sold wholesale or didn't carry any of the B&N cals I wanted.
It's slowly coming back to me--since I'm old and can't remember nuthin' anymore

-- about 5+ years ago, I noticed that whenever B&N sent a coupon they were starting to have the coupon be worth more (or only work at all) if you used it in the store. I griped about it on another website & somebody said, "Oh all these places that still have brick&mortar stores are doing that now; they know more impulse buying happens when you're physically in the store." Sign of the times I guess.
Back (kind of) to what this thread is orig. about, I love wall calendars. I know I can use the calendar on my phone, but I like looking at the pretty cal pix on my wall. But as was said above, wall cal's are prob. being phased out because of more & more using their phones or computers. And I have noticed that they are fewer & fewer free cal's being offered by businesses; I used to get so many free cal's in the mail or sitting next to cash registers of stores I went in, that I'd be giving 'em away. Not anymore.
And another thing--I promise I'm almost done

--looking online for the calendars: boy, there's a lot of weird ones for sale, dogs pooping, cats pooping, naked rugby players...

You know, I've quit using the expression,"What's this world coming to?!'" because I'm afraid I know.
