I combined the "Buy 4" discounts with coupons (printable coupons from Coupons.com) and Safeway's U savings (online savings loaded to my card). I had a raincheck for ice cream. There was a U Savings coupon for $5 off if I spent more than $25. Though Albertson's and Safeway are the same company Safeway has the addition money saving coupons.
I then loaded my receipts to Ibotta, SavingStar, and Checkout 51 for an additional $3.25.
It takes come planning looking at the sale flyer, looking for coupons to match, making sure you have the correct amount to get the buy 4 discount. If you do not have 4 of the correct items that will really mess up your savings. Make sure to have a backup 4 items if the items you are looking for are not there.
These apps are really easy.
