Readers Question: What's a Good Price for Diapers?

A reader is putting together her price book and wants to know what a good price on diapers is.

If she was asking about frozen pizza, snack crackers or something else my teen devours before I get it put away, I could help her out. But, I can't even remember what I paid for diapers in my day. Cost of diapers must be something like childbirth.  You quickly block out the pain.

If you a diaper buyer, what is your stock up price? 
Where do you find the best deals and on what brands?

Do You Have Or Use a Foodsaver?

I've been looking at maybe purchasing a FoodSaver.  I think they run about $70 at at Target, and now, Redplum has a $10 off any FoodSaver Vacuum Sealing System coupon available. 

It's not so much the price of the machine that has stopped me from purchasing one, but the price of the bags.

Does anyone have a FoodSaver?  Are they worth the money?  Which model should I purchase if I do buy one?

Help!
