I was just told that they would not price match HH Gregg for the 65ST60 because it's on Clearance.
This is from their policies:
Where the Guarantee Does Not Apply
Competitors' special promotions such as rebates, gift certificates, store-credit, "buy one, get one" offers, or bundled products are not eligible for the Guarantee.
The guarantee does not apply in cases when the customer has claimed a promotional offer from Amazon (e.g., an Amazon Gift Card or bundle) of equivalent value to the competing offer.
Time-limited sales events (such as Lightning Deals, Goldbox Deals, Black Friday, "early bird" or "door buster" offers, 24-hour sales), offers advertised as limited in quantity, clearance, liquidation and going-out-of business sales, and loyalty program offers are also ineligible for the Guarantee.
The Guarantee applies to the price payable for TVs only. Offers for or including ancillary services (such as financing, installation, or extended warranties) are not covered by the Guarantee.
The competing offer must be currently available in the model, color, and style that is sold by Amazon.com and the competing offer must be in-stock and available for purchase on the competitor's website, in new, unopened condition. Used, returned, open-box and display items are not eligible.
The Guarantee does not apply where the competitor or Amazon.com has made a pricing error or typographical error on an item.
The website featuring the competing offer must not be an auction site. The competitor must be operated by a U.S. company and must ship products from a U.S. location.
I don't know how I could have missed that before.
