5 Amazing Costco Buys for Spring Under $25

With the first taste of warmer weather hitting much of the U.S. this past month, many of us have already started planning for our time outdoors this spring. And while Costco is known for its incredible savings on homegoods and groceries, many people may be missing out on their seasonal offerings. From gardening to backyard barbecues to beach vacations, Costco has some incredible spring finds for under $25.

1. Swimwear

Whether you'll be at the lake, the beach, or the water park, chances are you'll need a swimsuit this spring and summer. But swimwear can be costly. A brand name swimsuit can easily cost you $70.00 or more, which is why Costco is a fantastic option if you're looking for budget swimwear. Costco carries brand name swimsuits like Hurley, Jessica Simpson, Speedo and Lands End at reasonable prices. For example, a Hurley ladies one-piece swimsuit goes for just $21.99, while men's Hurley swim trunks start at $18.99.

2. Water bottles

Even if you're the plastic water bottle type, nobody wants to sip out of a bottle that's been boiling in the sun. And let's be honest -- few of us probably want to contribute to the mass of plastic waste in the ocean. Fortunately, Costco sells a 2-pack of ThermoFlask 24 ounce insulated water bottles for $18.99, which is about $2.00 to $4.00 cheaper than other retailers like Walmart and Amazon.

3. Sunscreen

We've all been there -- you get back from a long day out in the sun only to realize you look redder than the backside of a baboon.

Luckily, Costco sells sunscreen in bulk, helping you stay stocked up. For example, right now, you can buy two eight ounce cans and one bottle of Banana Sport SPF 50 for only $13.99. For comparison, Amazon sells two eight ounce cans of the same sunscreen for the same price.

Just be sure to bring a bottle to a hotel or resort, as you don't want to pay resort prices for sunscreen, which can be double or triple the price you'd pay at the store. This happened to me recently, and I ended up paying $40 for a single bottle.

4. Beach towels

If you are a frequent pool- or beachgoer, you know you can never have too many beach towels. If you're due for a new stash of towels, Costco sells them starting at $17.99. And in typical Costco fashion, you can save when you buy in bulk. A set of two oversized beach towels is just $19.99. For comparison, you're looking at paying about twice that amount for a similar style and size at Walmart.

5. Allergy medicine

If you are one of the 80 million Americans suffering from seasonal allergies, this one's for you. Costco's Kirkland Signature NonDrowsy AllerClear Antihistamine 10mg tablets are $11.69 for a pack of 365, which is roughly $0.03 per tablet. Meanwhile, Amazon sells a similar product (GoodSense Allergy Relief Loratadine Tablets) for $12.99.

All in all, shopping at Costco can help you save money on your spring or summer essentials. And if you have yet to book your summer travel, don't overlook Costco's vacation packages, which can save you hundreds of dollars on your credit card bill when planning for your next trip. You can even get 2% cash back as a Costco Executive member, helping you save even more on your next summer vacation.
