Shopping at Costco is not for the faint of heart. The aisles are massive, the weekend crowds are huge (which is why you should consider weekday trips), and there’s just so much to look at. It’s pretty inevitable: You go in expecting to buy a rotisserie chicken and some frozen foods, and somehow you also walk out with a TV, a few new sweaters, and Christmas decorations you’re not 100% sure you need. If it’s your first time shopping at Costco, it can be a little overwhelming. Luckily, a few pros recently took to Reddit to share their best tips for Costco shopping.

1. Always get a cart

Always, always grab a cart when you go in, even if you’re convinced you’re only getting one thing,” warned lead injection.

2. Get the rotisserie chicken

 User iWillNeverReplyToYou put it succinctly: “1. Always get a rotisserie chicken. 2. Never not get a rotisserie chicken.”

It really is that simple.

3. Have a list (but know you probably won’t stick to it)

“I’ve been a member for 17 years. One time I came out with only three things! Of course, I went in for an eye exam…” joked ZephRyder.

DrizzitDerp had this helpful tip: “Prior to inflation our budget/list had a line item for impulse buys with a $ amount. I found it an amusing way to satisfy both random purchases while maintaining a budget.”

4. Know what the prices mean

Redditor AverageCowboyCentaur shared this handy guide:

  • Ends in .97 — Clearance
  • Ends in .88 — Discounted
  • Ends in .00 — Bigger discount, clearance
  • Ends in a 9 — Normal Price
  • Has an asterisk (*) at the end or top left of tag, item won’t be restocked

5. Consider the executive membership

 Redditor cpcxx2 shared their story. “The executive membership is $120 but gets you a shop card at renewal for 2% of everything you spent in the last year,” they said. “My check was $520, which blew my mind until I realized I got all my groceries, a vacation, countertops, carpet, and appliances for a new home, all my gas, and two sets of tires there — all while saving big on all of these items AND stacking many of them with the Costco citi credit card, which gets you another 2-4% cash back on everything.”

CeeGeeWhy added, “The executive membership gets you 2% back on front register and online purchases (some exclusions apply, gasoline, alcohol, tobacco, etc.) so if you do spend over $3000/year or $250/month there, it’s worth upgrading.

6. Expect to spend more

 And no, it’s not just because of those impulse buys.

“Pro tip: be prepared for a larger than usual grocery bill when you go,” said howsadley. “When I go to my local grocery store, my bill is about $100+, and the groceries last me about a week+. When I go to Costco, my bill is $350+. But the groceries last me about a month. I definitely had sticker shock on my first trip.”

7. Make sure you have adequate storage space

“Buy a vacuum sealer and a chest freezer. That way you can truly take advantage of buying large quantities of fresh items,” said Beard_o_Bees. “Unless you have a huge household, it’s the best strategy to avoid any kind of waste.”

Redditor boojieboy agreed. “This is the way. I think making Costco an effective part of your life requires having adequate storage space for things. The savings on any one or two items may be a few bucks, but the savings on dozens of items will add up to hundreds of dollars (over several years it will be thousands), so long as you don’t end up having to throw out unused stuff. For my family, dry pantry storage is part of it, but what really makes our system work is a chest freezer in the basement.”

8. Bring the right form of payment

Redditor DollarStoreKardashian noted, “Make sure you have a Visa [credit card] or your debit card with you. Costco doesn’t accept Amex, Discover, or [Mastercard].”

9. Consider Costco’s travel packages

 Not only will they help you make the most of that executive membership, but shoppers swear by their deals.

“I only do mine through Costco now — great cruise packages and stuff like that,” said sunrayylmao.

10. Bring your own bags and totes

If it’s your first time shopping at Costco, you may be surprised to find that the store doesn’t have any shopping bags at checkout. For the newbie shopper, this can create some trouble when it comes time to load and unload your groceries from the car. According to Costco’s site, the reason they don’t provide bags is simple: they keep Costco’s amazing pricing low. “Not only do shopping bags contribute to waste, they would also result in higher operating costs—and, ultimately, higher product pricing,” says the wholesaler.

So, when venturing to Costco, bring your own bags or totes to organize your groceries. While some Costco locations do provide cardboard boxes, it’s not guaranteed. Additionally, you will have to bag your groceries on your own, but that’s all part of the Costco experience!

Once you’ve read this checklist, you’re ready for your first-time shopping at Costco (don’t forget to try the free samples).

Chicken is a fan-favorite food, and for good reason — from barbecue chicken to chicken quesadillas to chicken parmigiana, it’s a lean protein that serves as the centerpiece for so many different meals. Consider this: In the early 1970s, per capita poultry consumption in the U.S. was almost 50 pounds; these days, it’s more than 100 pounds per person.

Of course, chicken hasn’t evaded the raging inflation that’s hiking up expenses every time we go to the grocery store (or gas station, shopping mall, or — well, just about anywhere.) According to the USDA, wholesale poultry prices are predicted to increase between 19-22% this year.

The one thing we love about Costco is that we can buy the things we love in bulk. The one thing we wish Costco would change? It forces us to buy things in bulk. We know, it’s the ultimate catch-22 of first-world problems.

Croissants from Costco are some of the best you can buy, which itself is a weird statement. How is it that a warehouse store has baked goods that are better — and often fresher — than a lot of local bakeries? We love Costco croissants, but most households can’t get through 12 big croissants in a few days’ time. What can you do?

If you love Costco as much as we do, you probably think there is no bad time to hit up the superstore. But if you're looking to avoid the rush of people and long lines, there are better times to go than others. As many know, Reddit has a wealth of information about Costco under the subreddit r/Costco, where droves of shoppers log in to ask all sorts of questions — from the best deals to their favorite purchases. One recently asked the question: "What is factually the best time to go to Costco? Weekdays, weekends, sunny, rainy, snowy days?" and the answers do not disappoint.

The best of the best
Of course, it wouldn't be social media without some entertainment thrown in, and this question got plenty of those responses. The most popular: "When you are craving a hot dog." While it's funny, Costco makes headlines for never increasing the price of their hot dog plus soda deal in the 40 years it's served up the tasty treat (which can be yours for the low price of $1.50). Another happy shopper recently found another good time to go: "Apparently during [the] Super Bowl." Makes sense.
