Meijer has an Mperk for 50% off 1 TI-84 CE right now. That brings them to $67.50, which is a great price. I've been told the Santa Bucks will also work on it, so another $10 off? Or more, if Santa Bucks go to the regular price. Great deal either way!
My kids all got these for Christmas in pre-algebra. They have them available at school, but they like having the same one at home to use. And it's an allowable calculator on the ACT and SAT, so they go in with one they can use. DD and DS2 have loaned theirs out to DS1's friends for testing this year, because the school does not have enough to use for all 11th grade kids testing at once.
