when to use coupons and when you are throwing your money away.

Coupons are the devil some of the time and a savior others. they can bring prices of goods down by a significant amount and in some cases bring the price down to free. the problem with coupons is knowing what you actually use and what your buying because its got a coupon associated with it.
I've often been to yard sales where people are trying to re sell their hordes of tooth pastes and deodorant thinking that they can make a quick buck off what they probably got for free. don't be this person, only buy what you can use within a reasonable amount of time. tooth paste isn't stocks they wont increase in value the longer you have it.

coupon sites are numerous and with the coming of the age of smart phone are even more accessible to most people. one website that I've heard of time and time again is The Krazy Coupon Lady where she lays out what is on sale and how to combine coupons to reduce the price down to pennies on the dollar. but again If you buy 500 tubes of toothpaste then you are still stuck with 500 tubes of tooth paste and significantly less storage.

Another place that you can sometimes find better deals is on  Amazon  and they also offer a subscription to product you have to buy on a regular basis which can save you time and possibility money. I used this extensively while I was overseas to order coffee and I often could get a great deal of coffee for very little money.

There are several other apps available on your phone, Ive used a hand full of them but I don't buy nearly as much as most people. A quick search on Google play or your app store of choice will reveal what option are available

The bottom line is  know what you will use, know what you can acquire for very little money and balance  out you expenditures. I have a set amount for groceries a month and I rarely exceed it But that is a discussion for another post
