Help please!!

Best thing you can do is get some comfy clothes on, a nice cold soda/hot coffee and plan to read, read, read and when you think your done, there's more reading. It doesn't happen overnight, but it is worth learning HOW to coupon.
Yes, you try and use a coupon for EVERY item you buy! 1 coupon is nice for 1 item bought. 50 items bought with 50 coupons, huge score!!! You most likely won't ever have a day with a coupon for every item, but when you get many, its awesome.
Coupons say Do Not double or Triple on them. Some areas of the country double the amount of the coupon value. Some even triple the amounts. Find out your coupon policy after you have done some reading. Good luck to you!

It is up to the store whether to double or triple or not. Some coupons will even say do not double on them but some of the stores in my area will double them anyway. Up to the store. Sometimes up to the individual cashier to decide.

Usually if the store doubles coupons they will say so in their ad or post it in the store. If in doubt ask a cashier or manager. Some stores never do it. Some do it one or two days a week. Some do it rarely and when you least expect it. Just keep watching and checking. Even if your store doesn't double there are good deals to be had with coupons.

Some stores like Walgreens will let you combine one of their store coupons with a manufacturer's coupon. Also stores seem to be changing their practices all the time so be flexible. Sometimes it is cheaper to buy a generic without a coupon. No matter what the "asking price" or starting price is it isn't the amount off that matters, it is what you end up paying for the product unless you need a certain brand or product.
