Ok this seems like a pretty good deal to me!
Right now Best Buy has the Tinkerbell Blu Ray on sale for $16.99. You can head over HERE and log in or create a new Disney Movie Rewards account. Once you are in- just look for a box on the right side that says enter code. Enter the word GIFT and you can print a coupon for $10 off Tinkerbell. So that makes the Blu Ray $6.99 which is a great price!
Then you can head over to Amazon HERE and order the Leapfrog Tinkerbell Tag Book for $9.99. If you have Prime the shipping is free.
Once you get your order confirmation just print it out and mail off the Amazon receipt and the proof of purchase from the back of your Blu Ray HERE.
So you will pay $6.99 and $9.99 but you will get a $5 rebate back making both items $11.98!
