Barnes & Noble has "Educator Appreciation Week" every so often, and sends me e-mails when it's time for me to get additional discounts on anything I want to purchase. I try to wait to buy personal items (non-classroom books) until this week because the discount is actually better than the usual one for educators*. But I love the grammar error sent out on this e-mail announcement!
*If you're an educator - even a homeschooler - you can sign up for the educational discount at no charge at B&N. Just ask at the check-out, and they'll set you up. Then, everything you use for school is 20% off. For homeschoolers, this covers a lot of materials, considering how integrated lessons can be.
