Using money wisely

With all the raising of prices for gas, food, and other products the list never ends. My husband and I both prefer certain places to shop, but sometimes I think we need to learn how to put things to good use. Yes it may not be from one of our favorite stores but shoot it may save us money and it’s the same brand.
We are to be responsible with our money. Yeshua made this clear with the story of the talents, the one who invested in it was rewarded.
Yeshua story tells us we aught to be responsible with what we get. I used to use coupons for grocery shopping but I don’t do it a whole lot. When I was getting the news paper or receiving it in the mail, I would use those coupons. I will sometimes look at different stores on line to make sure I get the best price, sometimes they are all the same price list.
I know G-d has provided many times in different ways. Sometimes I wonder if he some how places the idea in people mind to put things on sale so that when I need Circuit City coupons they get a product on sale that I need. I do believe G-d can place ideas and thoughts in our minds.
