The 5 Best Deals at Costco for Under $100

It's no secret that Costco can give you the best bang for your buck -- or your Benjamin. Every month, the warehouse runs promotions, deals, and ongoing savings that can give you more value for your $100. Some promotions are pretty terrible or are already out of season -- like these garden beds for $99.99 -- but others are surprisingly good. Let's look at five Costco deals that have recently caught my eye.

1. Gift cards

Costco gift cards are probably my favorite deal. Many of Costco's gift card packages are valued at $100, but will sell for 10% to 30% below that price. To give you an idea of its variety, here are a few gift card packages you can buy on its website:

You might even find better deals at your local Costco warehouse. For instance, I found Miller Paint gift cards at my local store ($100 of value for $69.99), which impressed me given that paint is pretty expensive. This deal likely won't be found everywhere -- Miller Paint is a Portland-based paint company -- but you might find other local businesses offering good deals at your store.

2. Belkin wireless 3-in-1 electronics charger

This one definitely had my attention. This is a Belkin 3-in-1 wireless charger. It can hold your phone in one arm, your smartwatch in the other, and still charge another device at its base. Most retailers are selling this Belkin wireless charger stand between $130 to $150. Costco is currently selling it for $84.99. That's a savings of $45 to $65.

3. College football tickets

Another incredible deal, Costco sells pairs of college football tickets for super affordable prices.

It doesn't sell tickets for every university and, where it does, it will limit members to a certain number of tickets (like 5 vouchers or 10 tickets total). But from what I can tell, the savings can be between $40 and $50.

Here's a random samplings of three college football tickets that Costco sells:

4. Halloween costumes for kids

Costco's Halloween costumes are ridiculously cheap -- and pretty adorable. It sells a variety of Teetot full costumes, ranging from ninjas to dinosaurs to fairies and astronauts and Disney princesses. Most of its costumes are below $35, so if you're shopping for two, you can still keep your Costco deal under $100.

5. Gourmia air fryer

This Gourmia 7-quart digital air fryer is selling on Costco's website for $47.99, but you'll likely find it cheaper in-store. In fact, I bought this air fryer back in May for $39.99 (regular price of $49.99, plus a $10 discount). For perspective, this same air fryer is selling on Amazon for $109.99 -- and that's with a 13% discount!

These are just a few of my favorite Costco deals under $100. They won't all be the best decision for your personal finances, but if you're already budgeting for them, they can sweeten the purchase with a little savings.
