Pissed? Not really - yet.
I have emailed and contacted Best Buy through Facebook and Twitter. I will also contact my local store today. Actually, I am printing out the promo and going taking it to my Best Buy store on the way home. I am buying my Flyer today.
I know they may not be able to match another store - but it is worth a shot. What they will do is this - price match. Best Buy has helped me out several times with this. I bought a laptop for my wife a couple of years ago. A month later, the same laptop - same price, but it came with a FREE Wii system! Free! So, I took my receipt back and they gave me a Wii on the spot.
Back in 2009, I bought my Palm Pre for 200 bucks. A couple of months later, they were selling it for 99 bucks for a weekend sale (which turned out to be a company-wide pricing mistake). I took my receipt to customer service, and they refunded my credit card the hundred bucks on the spot!
So, what I am saying is - maybe soon this free pen promo will hit your city. For me - it is Atlanta. When it does - take your receipt back to Best Buy and they will (most likely) honor the special and refund your initial pen purchase. OR give you another pen - which you could resell or keep as a back-up.
If I hear any good news - I will reply back here.
