Best Buy has it for $19.99 you can either just use the coupon there or price match at Target. Not sure of Walmart's price but I believe they also price match (if need be).
Target has the Blu Ray Combo Pack for $22.99 but here is how to get it for $9.99! Remember even if you do not have a Blu Ray player this will more than likely be the cheapest way to get the DVD (combo pack has both Blu Ray and regular DVD).
First print your coupon here use this code : 786936801811
Grab your Best Buy ad to price match.
Then go to Target and pick up your copy of the Blu Ray combo pack.
Take it with your Best Buy ad and your coupon you printed and go to Guest Services.
Have them price match it to your Best Buy ad and voila it is now only $9.99 for the 2 disc set which is a lot cheaper than buying just the regular DVD. Again which is why I recommend buying it this way (who knows even if right now you do not have a Blu Ray player who is to say that say within the next 2 to 4 years you won't?).
So you will spend $9.99 plus tax for a 2 disc set (including both the Blu Ray and regular DVD) of Alice In Wonderland (cartoon Disney version). That is a very good price!
