Amazon offers Prime members Everest on Blu-ray / DVD / Digital HD for $4.99 with free shipping. (Best Buy charges the same. Non-Prime members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's the lowest total price we could find by $1.
Amazon had Everest on sale today as lightning deal for $7.99. I purchased it. I noticed several hours later that Everest had been dropped to $4.99. I clicked on it and the lightning deal was over. I immediately went to cancel my Everest Blu-ray that I paid $7.99. I went to purchase for $4.99 on Amazon, but it said it could take 1-2 months to arrive. Had that happen in the past and Amazon cancels my order after waiting a few months saying wasn't able to fill my order. Therefore, I didn't purchase on Amazon, but on Best Buy's website for the $4.99 price. Hopefully people that purchased at more expensive lightning deal saw the cheaper price and also canceled to get it cheaper!
I purchased a movie from Amazon that I received on Tuesday. I noticed yesterday that the price had dropped from $9.99 to $6.99. I tried to get a refund for $3.00 for the price difference, especially since none of the prices were for lightning deals. No refund so I wasn't going to lose money twice!
