Tried this on a Vita. Online you can stack this, the 10% wish list, a registry one if you have one, and TGTA39R9 which knocks off $5. Without the registry, it's $157 before tax and redcard which is pretty good buuuuuuuuuuuuuuut
In store, Cartwheel has a 15% off Vita code so you should be able to stack the 10% today off in store, the cartwheel, and the redcard for 30% off which should be around $140. not sure if you could use the 10% off wishlist on top of it as I am not sure if the 10% off today is considered a store coupon or not. If they price match Groupon, then you could start at a base of $171 and try to work the 30-40% from there.
