I spend many hours each week grocery shopping. Prices are changing daily at numerous stores. Right now pineapples range from $1.29 to $4.00. The two for sales are clever as they increase the single price before they offer 2 for 1. Packaging is another scam. Reduce amount of item in package so prices stay the same. Ice cream doesn’t come 1/2 gallon anymore and potato chip bags are full of air. Gasoline used to change a penny or two once in a while. Now it can change 30 cents a gallon in one day. Very difficult to go shopping now. I feel you need a degree in economics to shop nowadays.
