1. You can combine — or stack — coupons and promo codes
There are various categories of discounts options at Kohl's, which include sitewide discount codes, discounts or coupons for a specific item or department, free shipping codes, and reward codes like Kohl's Cash.
Streeter said that one of the best ways for customers to save at Kohl's is to combine — or "stack" — up to four coupons per purchase to get the best value.
2. You can get $10 Kohl's Cash without spending $50
Streeter said that as long as your purchase is within $2 of the amount required to get Kohl's Cash, you will still qualify for it.
"Please note your total must be AFTER discounts and before tax or shipping charges," Streeter said. "So go ahead, spend $48.01 and earn that $10 Kohl's Cash!"
According to the online shopping blog Penny Pinching Mom, you can also combine receipts from different trips within a promotional period to get Kohl's Cash if your individual purchases do not hit the required number in one trip.
3. Expired Kohl's Cash can be still be used in some cases
If you have the physical voucher of your expired Kohl's Cash, you can still likely use it in stores if it has been expired for fewer than 10 days.
Streeter said that if the cashier doesn't accept it, you can tell them to call corporate, and they'll likely say it is fine.
"I have done this on numerous occasions even since they started to say they no longer will accept expired Kohl's Cash," she said.
4. Sometimes it pays to shop late at night or early in the morning
Kohl's occasionally runs night owl and early bird specials, where prices can be up to 25% lower than the average sale prices, Streeter said. These sales will usually run on Fridays until the store closes from 3 p.m. local time and on Saturdays from store opening until to 1 p.m. local time, Streeter said.
"Hot Tip: If you shop online, these hours will be extended," Streeter added. "I live in the Midwest (central time) so during Early Bird Sales I am able to shop online until 3pm CT."
Shopping blog Retail Me Not mentioned the time-bound discounts in a blog post and wrote "This event happens several times per month, too, so make sure you're watching for when these discounts happen."
10. And for customers over 60, Wednesday is the best day to shop.
Kohl's offers a 15% discount in stores every Wednesday to customers over 60 years old.
"Even better, you are able to stack these discounts with other department-specific saving coupons," said Streeter of the military and above-60 discounts.
11. Shipping can always be free, if you do it right
If you order items in stores at a kiosk or connect to the store's WiFi through the Kohl's app, you can get free shipping on your order.
"PLUS when you are connected to their WIFI [sic] through the Kohl's App sometimes a random percentage-off or $5 code will pop up to use!" Streeter said.
12. Use the Kohl's app to save more money in the store
The Kohl's app is designed to keep track of discount codes, gift cards, and Kohl's Cash.
If you are shopping in the store and you can't find the right size, you can order the item through the app in the correct size and get free shipping.
Streeter says another great perk of the app is the ability to get notifications that include "Secret Sales" and "Mystery Offers."
13. Get the Kohl's credit card for even more savings
Streeter said that Kohl's credit card holders can get up to 30% off sitewide about 12 times a year. Any sale larger than that will include free shipping.
Additionally, Kohl's credit card holders who spend $600 a year become "Most Valued Customers," which means they are eligible for offers like a birthday gift and free shipping events.
"If you shop at Kohl's often, their credit card may be for you," read a blog post on shopping blog Retail Me Not. "You'll get 20% off your first purchase right off the bat, and then you get a new coupon at least once a month for 15% to 30% off your purchase."
14. For non-Kohl's-credit-card holders, watch out for mystery savings
Streeter said that on the last day of a 30% off sale, customers on the store's email list will usually receive a "Mystery Savings Code," which is generally a 40%, 30%, or 20% off sitewide code.
The Yes2You rewards program lets customers earn one point for every dollar spent. Members also get a $5 reward for every 100 points earned and are eligible for a special birthday gift and events where they can earn bonus points.
"PLUS, several times a year [you can] earn double or triple rewards points," Streeter said. "Remember too that Yes2You rewards are earned on all purchase[s] like Kohl's Cash!"
