I work at Spirit Halloween. Here are 9 mistakes I see customers make when shopping for costumes and decor.

• I've worked at Spirit Halloween for three years and have seen many customers make the same mistakes.
• I always encourage shoppers to invest in high-quality pieces they can reuse year after year.

Halloween has always been more of a lifestyle than a holiday for me, much to the chagrin of my husband and family.

Although this is my third season working for Spirit Halloween — the seasonal chain known for taking over empty storefronts — I've been a longtime customer and have even joked that the store was created just for me.

Here are nine mistakes I see customers make while shopping for their costumes and seasonal decor at the popular Halloween chain.

Going straight for the lowest price instead of investing in quality pieces

If you only plan to wear a costume once, it's fine to go for the cheap stuff. But investing a little more can extend the costume's wear.

Spirit Halloween offers a line of Signature Collection costumes, which cost more but are made with higher-quality fabrics. I've found these pieces can last through several years of Halloween events or cosplay fun.

Investing in great accessories to complete the look is just as important. For example, if you're dressing up as a vampire, fangs can add an extra layer to the costume. However, a cheap pair of fangs probably won't last the night.

My personal favorite is the Scarecrow brand of fangs because they come in different sizes for a more custom fit.

Buying makeup kits without proper application and removal products

Makeup can really elevate a costume's look, but let's face it, most Halloween-store makeup isn't top quality. I recommend protecting both your skin and your look by investing in quality products like primer, setting powder, and heavy-duty setting spray.

If you're using prosthetics, be sure to purchase Spirit Gum adhesive and remover. Without it, removing prosthetics can be difficult. And you definitely don't want to join that next-day Zoom meeting still dressed as Hellboy.

Failing to check makeup and prosthetics for irritants

Always test makeup and adhesives for allergic reactions by using a small amount of the product on the inside of your wrist. Wait at least 20 minutes to see how your skin reacts.

Before purchasing any products, read the package carefully and search for any irritants or allergens.

Not browsing the entire store

When shopping for accessories to complete your look, keep your eyes open and peruse the entire store because hidden gems are everywhere.

The checkout line, in particular, is always full of the best selection of chokers, earrings, and other fun novelty items.

Only coming into the store once per season

Never make just one trip per season to Spirit Halloween, as stores get truckloads of new merchandise delivered weekly. Chances are you'll find something new every time you come into the store.

I also recommend asking an associate on the sales floor when the next delivery will be. We're happy to help you find the latest products.

Failing to read the labels on animatronics

When purchasing animatronics, always make sure you read the box before making a purchase.

A lot of the animatronics are made for outdoor, covered use only. That means that they can break down from exposure to weather (especially humidity that can mess with the electronics) if left outdoors unprotected.

Not signing up for email and text offers

Most people are tired of receiving email and text offers, but Spirit Halloween's are worth it. By signing up, you'll get a 20% off coupon to use during your next visit.

You'll also receive exclusive emails throughout the year about new props and displays, and notifications when stores near you are opening or hiring.

Returning items before calling support

Most people don't realize that Spirit Halloween has its own tech support hotline. Before returning any electronics to the store, call the Zombie Tech Squad (their number is displayed on all prop directions).

Most times, they can troubleshoot your issue and save you a trip back to the store, which can be super helpful during the busy Halloween season.

Forgetting that we stay open after Halloween

Don't skip out on the clearance sales on November 1 and 2.

Two years ago, my store was still putting out new stock until closing on October 31. All of that merchandise is typically discounted by 25% to 50% the next day.
