Mamatothreewee: You need to get the Sunday paper, that's the single biggest source of coupons. Dollar stores sell them, I have heard. All You magazine (sold at Walmart), and also through subscription has high value coupons every month. Also watch free standing store displays and "blinkie machines" at the store and grab any coupons that you think you might use in the future. Trade with friends and family. Get the word out that you want coupons and people will save them for you. I rarely, if ever, *buy* coupons from websites unless it's something that I want to get a lot of and then I usually only pay 10 percent of face value.
Two websites that you will probably find helpful are www.couponconnections.com and www.refundcents.com. Amber at Coupon Connections lives in Lynnwood, WA and hosts couponing classes and coupon swaps. Her site is free. Since she is from Washington state, her site will be helpful for you since the stores and store sales vary by region. Michele from Refund Cents is from Utah and runs an amazing website. Her site costs $12 a year for online only access, but it is well worth it. Michele also has several trading boards where you can trade coupons that you have for ones that you need, or trade coupons for a handling fee or stamps.
Hope this information is helpful. You do need to know up front though that you will not be saving the kind of money that you see on "Extreme Couponing" the word "extreme" describes that show very well. I routinely save 50 percent or more off of my weekly shopping trips taking advantage of shoppers cards, store sales, store coupons and manufacturer's coupons by buying only what I know my family can use. Let me know if you have any other questions..
