Americans spend a frightening amount on Halloween.

According to an annual survey conducted by the National Retail Federation, the world's largest retail-trade association, Halloween spending is expected to reach $8.8 billion in 2019, including $390 million on greeting cards, $2.6 billion on candy, $2.7 billion on decorations and $3.2 billion on costumes.

The scary-good programs planned at all three Worthington Libraries locations this month can help you make the most of your Halloween holiday budget.

Want to save a bit on costumes? Try "shopping" for them at Worthington Park Library, 1389 Worthington Centre Drive, on Saturday, Oct. 19. During the library's costume swap, which starts at 2:30 p.m., visitors will browse clean, gently used costumes for all ages. If you have a closet full of unwanted costumes and would like to donate them for the event, drop them off with library staff through Thursday, Oct. 17.

The NRF's annual survey indicated that 29 million people intend to dress their pets up for Halloween this year, with anticipated spending for pet costumes at $490 million, more than double 2010's tally.

Whether it's a pumpkin, hot dog or superhero -- this year's top pet costumes, according to the NRF -- take your furry friend to Northwest Library, 2280 Hard Road, on Sunday, Oct. 20, for a pet parade. Dogs, cats and other pets are invited to model their howl-oween costumes and prance for prizes starting at 3 p.m. Animals must be leashed.

If you're going to spend money on costumes for your children, why not get as many wears (and photo opportunities) from them as possible during the spooky season? On Oct. 25, Old Worthington Library, 820 High St., will host its annual Pumpkin Parade. Children younger than 5 should come in costume for a storytime that includes singing, dancing and a parade around the library (weather permitting). This program starts at 10:30 a.m.
