I mistakenly held the Shift key when I typed in "4th" so it looked like "$th". Something about that... anyway, I hope you don't overspend and you don't get sunburned and you don't wear yourself out so it's hard to finish the rest of the week, but I DO hope you have a great 4th of July. (That day is also known as Independence Day, for those of you who are not from the USA.)
If you haven't yet, stock up on hotdogs and ground beef and BBQ sauce and picnic supplies. They're traditionally on sale right about now. Both hotdogs and ground beef keep well in the freezer, so take full advantage of those sales.
Have some free fun, too! July 4th can be a frugalista's heaven. This day offers free parades, free fireworks, cheap meals and lots of outdoor activity.
It can be costly if you opt for the carnival which many cities have this time of year. Take only what money you can afford to do without, because the chances are that you'll come out with nothing left. Eat before you go, drink lots of water so those expensive soft drinks don't appeal right away.
You don't need to spend a lot of money to have a lot of fun.
In all that fun, don't forget what the day is all about. This is still a great country, regardless of our problems and fears. There isn't a nation in the world like it. Celebrate that.
