UPDATE: Bah! Received a cancellation email from Staples. Thought about calling, but a friend of mine called and talked to customer service and the man flat out refused to give her the promotional price. She mentioned they were in stock online and he said it didn't matter. Not on back order. Not on any order period. Nice. Now to tell my girly girl she won't be Sharpie-ing it up any time soon. And here I thought I was going to be cool to her for like a whole five minutes.
UPDATE #2: Staples has contacted me via email and generously given me a $5 credit to my Staples account per pack of markers ordered. I did not request this, but appreciate it. I can say I am satisfied with this solution. As you can see my order only came to just over $6 so to get a $10 credit makes me happy. Hopefully this doesn't happen in the future. So check your email and see if you received the same compensation.
