Bertolli Sauce packets are on sale for $2 each. At many Safeways there are $1/1 blinkie coupons (the little machines that spit out coupons) right above the product. The sauce packets are also part of a promotion Safeway is having where if you buy 10 specially marked items you will get $5 off instantly.
So buy 10 pouches X $2 each - 10 $1 coupons = $10 - $5 instant savings for buying 10 = $5 oop (out of pocket)
BUT these sauce packets are spitting out coupons at the checkout (called Catalina coupons). For every 2 you buy you get one $2 off your next purchase coupon.
So, you spend $5 oop and you get five $2 off your next purchase coupons ($10 total) making this a $5 money maker. So, you get to walk out of the store with 10 pouches of bertolli sauce for free essentially with $5 extra you can spend on any other items in the store.
If you want more sauce you can then use those $2 off your next purchase coupons to go back and buy more sauce. The second transaction of 10 packets would only cost you $1 oop (using 2 $2 coupons and 10 $1 blinkie coupons) and then you would get another five $2 catalina coupons. You'd walk out of the store with 20 packets of sauce and a total of $6 (plus tax) oop expense and 8 "$2 off you next order" catalinas.
The Safeway buy 10, save $5 mix and match sale ends 3/30.
