Great thread, gg!
Off the top of my head:
Entertainment: Dollar theaters and Sunday morning shows for movies. Some theaters have an 11 a.m. or so show on Sunday mornings for half the price of a matinee show, usually about $2 or $3.
Fast Food: I know you family people do it once in a blue. Don't order meals. Order your sandwiches and then order an extra large fry to share. Bring your own water. We've been so conditioned to buy those meals but it's a helluva lot cheaper without those wasted fries and drinks.
Meal Planning: Don't do it until you've checked your supermarket circular to see what's on sale. If you have an inexpensive Sam's or Costco membership through the workplace, you can buy meat, poultry and veggies in quantity and save as well.
Hand-me-downs, thrift and consignment: I swallowed my pride years ago and am happy to accept gently used hand-me-downs for the girls. Great items can be found, some not even worn, from thrift and consignment shops. People with too much money to spend donate some nice stuff.
