For the past few weeks, I've been helping out a friend with weekly shopping for a neighbour recovering from a car accident that has left him temporarily in a wheelchair ... one item on the list is "Ben & Jerry's" ice cream.
Ice cream is not something I buy/eat, but it's surprising the price difference in different shops. It varies hugely ... much more so than anything else on list.
I'm not too careful when shopping myself, but the different for his list of shopping varies a good amount depending on the shop. Makes me think ....
