Buying in Bulk

Our neighbor who lives here part time from Kansas City does all of her shopping at Costco.
"The Green Year" gives a tip to buy in bulk when you can. It saves on packaging and while it costs more to buy the bulk items, it does save you in the end.
Some items that are best bought in bulk:
toilet paper
paper towels
women's hygiene products
pain relievers
vitamins
office supplies
soda
cereal
coffee
