The NEX has these DVDs/Blu-Rays for $30.99 and I don't know their policy on using internet coupons, but I got this from a reputable refunding site and it says it's good in the U.S. and APO/FPOs. It even gives an address online where it can be verified. It expires SATURDAY, so if you're going to buy it with the coupon, do it today or tomorrow. Here is the link:
I would ask the NEX if they will take the coupon first, unless you are going to buy it anyway and don't care if they say no. There is also a $10 coupon offer on the official Disney site if you are upgrading your current copy to the DIAMOND edition. You have to go in, join the movie rewards program (or sign in if already a member) and enter your old UPC from the VHS or DVD and they will give you a printable coupon. Here is the link for that coupon offer (can't use both) This one expires 10/19/09
You can also get another $5 back by sending in your DVD proof of purchase plus any Hefty brand purchase. Expires 1/31/10. Says it's good in APO/FPOs. Here is the link for that form:
So if you're in the market for this movie and you buy 1 Hefty product (and the NEX will take the coupon), you can get a total of $15 off the price of this DVD.
Happy savings :)
