For many people first trying couponing, one of the most challenging things is organization.
What works best for me is having a folder labeled "Manufactures Coupons". In the folder I have envelopes with dates of when the coupons inside them would expire and above the date i would have labeled the contents that are in the envelope for example, i would have "glade", "oust" and so on.
Next for the coupons that go to specific stores like target or sears i have separate folders. In those folders i would have envelopes with dates of which the coupons inside the envelope would expire.
