The air is getting cooler, the days are getting shorter, and Halloween is knocking on the door. Soon we’ll be putting away our jackets and pulling out our winter gear, but for now, we still have one last hurray to leaf-peep, carve pumpkins, go nuts with the cosplay, and stock up for the deep-freeze ahead.

Whether you’re shopping for giant bags of treats or getting a jump-start on the holidays, a Costco membership gives you access to low warehouse prices — and special members-only discounts.

Right now, when you sign up for a first-time, one-year Costco Gold Star Executive Membership, you’ll get a $20 Costco Shop Card (first-time Gold Star Members receive a $10 Costco Shop Card). Here are some ways to spend your Costco Shop Card — and get into the fall spirit.

Outfit your tiny trick-or-treaters

Get the kiddos ready with nicely priced costumes with a ton of details like a colorful witch ensemble ($32.99) featuring a hat, broom, and flashy sequin trim, or a cool astronaut spacesuit ($32.99) with a helmet and boot covers (these lucky tykes probably will vacation in space one day). You can also score member pricing on a handy Ring video doorbell to see the masqueraders at your door.

Get your fall spirit on

Welcome guests with a friendly monster greeter ($29.97) featuring a lighted LED pumpkin or hang a fall harvest wreath ($49.99) with faux sunflowers for a seasonal look. Prefer fresh blooms? Treat yourself (or someone else) to a pumpkin-shaped vase ($45.99) filled with orange roses, burgundy mini-carnations, and pieces of foliage.

Light up the night

Set the mood for a pumpkin-carving party or deck out your patio with two ornamental lanterns ($49.99) with warm, flickering LED flames you can use indoors or out. The candles have a timer function for six hours on and 18 hours off. Or, light up some Sand + Fog scented candles ($37.99), order delivery, and stream a scary movie for a spooktacular Halloween night in.
