If you have a Nebraska Furniture Mart close to where you live (Omaha, Kansas City or Des Moines), you can try to price match at your local Walmart or Target store. This movie is being released on 11/23 and there is a coupon for $10/1 Santa Paws Blu-ray DVD combo pack. NFM will have this set for $16.79 when it is released, use the coupon and get it for $6.79 at your local store.
You can also request duplicate receipts and can even submit two different rebates, which could in essence turn this into a money maker! Remember that some stores may not price match as the offer is limited to 1 purchase or will consider it a special offer promotion – but it never hurts to try!
