A couple things I learned at a couponing seminar and some things I already knew.
With buy 1 get 1 free deals, use 2 coupons. I always do this! I get a lot of items VERY inexpensive this way.
Take advantage of companies that accept competitors coupons.
If something is on sale in an ad and they run out, get a rain check and staple your coupons to the raincheck. Even if the coupons expire before you redeem the raincheck, they will still accept those coupons!
Some places price match (like walmart) but the prices MUST be advertised. Publix never puts their prices in the ads!! At least not on their B1G1 items.
What are your tips?
