Cloudy with a Chance of Meatballs goes on sale Tuesday Jan 5th. Best Buy and Target both have the DVD for $15.99 and the Blu-ray combo pack for $24.99. I would lean towards Best Buy since you can earn points through their reward zone program. There is a $3 off coupon that would bring your total down to $12.99 for the DVD and $21.99 for Blu-ray.
There are also some rebates available:
Free Spot Shot mail in rebate with purchase of movie. Use $1 off coupon for Spot Shot from 1/3 SS.
Or, if you would like to try to get a free copy, Buca di Beppo is offering a limit number of Free DVD’s with a purchase of a Meatball Pizza. You can use a $10 off a $20 purchase with coupon HERE or in 1/3 RP (regional).
