Due to their recent snafu Target is having a 10% off storewide sale this weekend. They currently are selling 3DS XL bundles for $149.99. I can confirm that this 10% off will stack with that discount. In addition, you can use a 5% off card if you have one.
Brought the "Mario and Luigi Dream Team" 3DS XL bundle down to $127.49 +tax for me.
