On January 8, 2013, Target announced that they will PRICE MATCH against Amazon.com among others. So even if you DON'T buy things on Amazon, being unaware of Amazon prices will hurt you.
Or conversely, if you want to save money in Target, take your smart phone and check Amazon pricing. If you find things cheaper on Amazon, then make sure you get your Target price break.
Here is the actual Target policy statement “If you buy a qualifying item at a Target store then find the identical item for less in the following week’s Target weekly ad or within seven days at Target.com, Amazon.com, Walmart.com, BestBuy.com, ToysRUs.com, BabiesRUs.com or in a competitor’s local printed ad, we’ll match the price. Price match may be requested at Guest Services prior to your purchase with proof of current lower price or by bringing in your original Target store receipt and proof of the current lower price.”
