Getting ready for my first "big" couponing attempt

So, I'm about to go to Target on my first "big" couponing attempt.  If I've calculated correctly, I should save over $50 and only buy things I currently need or things that are free and will use.  I will share later on what I got and how much I actually saved.  I spent 2 hours this afternoon getting ready and researching everything.  I hope I get faster as I get used to this!  Wish me luck!
