There are days when I don't have to pay three or four dollars for 4-ounces of blueberries. I can go next door to the 99-Cents Only store and buy 4-ounces of blueberries for $0.9999 (they raised their price by $0.0099).
Ditto lots of stuff, stuff that's available every day such as bread, fresh fruits and vegetables, name-brand packaged vegetable salads ($0.0099 v. $3.00+), milk, popular and name-brand deli products, tons of canned goods, paper products, everything. Don't worry about expiration dates either though it always best to check.
To be fair to Raley's they often have great sale prices on stuff that 99-Cents Only cannot not stock.
I'm always happy to give 99-Cents Only a plug. Dollar Tree is great also but 99-Cents Only is best for food stuff in my experience.
Correction to my reply above. Where it says “($0.0099 v. $3.00+)” that should be “($0.9999 v. $3.00+)”
