You can ask them to “order” books, movies, & CDs from other libraries. They lend to each other & your library will call you when your item comes in. How nice is free? Have movie night at your house for the price of your made-at-home popcorn.
Many libraries have current best sellers also. Since your tv is a huge elecrticity waster, if you read a book a couple of nights a week instead of watching tv, you’d save on your electric bill too!
You can check out cookbooks, try some of the recipes, & see if it’s really worth buying your own copy.
You can learn about places you might want to travel to. You can read lots of finance/budget self-help books for free too.
Some libraries have sewing patterns that you can borrow for as long as you like & even keep if you want to.
Have guests coming & some bare walls? Our libary has paintings you can borrow.
Most libraries have a story time for pre-schoolers. Older kids can join the summer reading challenge. There are usually lists of books that college-bound kids should read. Not a bad way to spend some summer days.
You can have a relaxing hour reading newspapers and magazines at the library without paying a cent.
Community events are often posted at the library, so you might find out about some cool free activities.
Some libraries have a coupon exchange box where you bring what you won’t use & take what you will. If yours doesn’t have one, suggest they do. You could make up the box & sign for them to make it easy.
It might be an exaggeration to say your library is a gold mine, but it certainly can save you real money.
