If you order online, it's still $79.99 though, right? The discounted price of $59.99 is only in-store and the $54.99 price is only in-store with the coupon?
Right... but you should be able to take care of all that stuff when you arrive to pick up the set at the customer service desk, since they don't charge your card until you show up and buy it (you'll initially see a phantom charge for the amount that will disappear after a few days). Just bring the ad and a DVD with you to trade in and the price will be adjusted down from $79.99 (plus tax) to $54.99 (plus tax).
Here's the Price Match Guarantee from BestBuy.com:
How does your Price Match policy apply to purchases made using store pickup?
If you purchase an item at BestBuy.com (which includes a purchase from a smartphone application/website, BestBuy.com orders with store pickup, and orders from the kiosk inside a Best Buy store) and if the item is offered at a lower price in the store when you pick it up, you will automatically pay the lower price.
I think you guys need to read the ad more carefully... If you look closely, I think what they're selling for $59.99 is tickets to see the screening of the two episodes. That's why it says "in theaters nationwide" and "Fathom Events" and "2 episodes plus behind the scenes." They just used the same graphic for the season 1 set. It's a somewhat deceptive ad, but I think that's what it's saying.
The tickets are only $12.50 each plus tax
