I have to share this because I know I have teachers and librarians that read the blog. So here goes - I'm a dork. I completely admit that! And here is just one example.
My students are always asking for bookmarks. I can't afford to buy the official bookmarks they sell in packs of like 25. Well one year I was standing in the Valentine's aisle looking at the stuff on clearance. I looked at the boxes of Valentines on 75% off and had a light bulb moment. They would make perfect (and cheap) bookmarks. I snatched up several boxes and put them out the next day. My students loved them. Now they could have a Spiderman or Harry Potter bookmark. You should see them dig through the box they are in looking for one they like.
So now every Valentine's Day I snatch up several boxes. This year I bought 15! But I did the math and I got 500 book marks for like $6! Here's a pic of most of the ones I bought.
Call me crazy but it works :)`
