If you shop online, you’ve probably noticed the wide variety of offers labeled as promo codes, coupons, or vouchers. While these terms are sometimes used interchangeably, each one serves a distinct purpose in the world of discounts. Knowing how each works—and when to use them—can help you unlock more savings and avoid missed opportunities at checkout. This guide explains the precise differences, common use cases, and best practices so you can navigate every sale with confidence, powered by expert insights from Giving Assistant.
Definitions: What Is a Coupon, Promo Code, and Voucher?
- Coupon: A discount certificate, usually in the form of a code (digital or printable), that gives you a percentage or fixed-amount savings on a particular product or category when used at checkout—either online or in-store.
- Promo Code: An alphanumeric code used primarily for online shopping that provides a special deal, like a percentage off, free shipping, bonus items, or cash back. These are entered during checkout and are usually time-sensitive.
- Voucher: A digital or paper-based document (or code) representing a fixed cash value, similar to a gift card. Vouchers are often used as payment and can be applied across multiple purchases until the value is depleted.
Step-by-Step: How Each Discount Tool Works
How Coupons Work
- Find a coupon (either from a manufacturer, your favorite retailer, or an aggregator like Giving Assistant)
- Check the terms—some may only apply to certain categories or brands, or require a minimum purchase.
- At checkout (in-store or online), either scan the barcode, show the physical/digital coupon, or enter the coupon code.
- The discount is applied instantly. Most coupons are single-use and can’t be carried over.
How Promo Codes Work
- Promo codes are primarily digital and found on brand websites, email newsletters, affiliate partners, influencers, and major discount platforms including Giving Assistant.
- To redeem, copy the promo code and paste it into the designated field at online checkout.
- Promo code discounts are applied before payment. These may be sitewide, category-specific, or tied to events (such as first-time buyer deals or flash sales).
- Promo codes are usually valid for a limited time—sometimes only 24 hours—so use them quickly.
How Vouchers Work
- Vouchers are typically distributed as rewards, compensation, or as part of loyalty or gift card programs.
- At checkout, enter the voucher code or present the physical voucher. It is treated as a payment method, deducting your purchase from the total value.
- If the entire voucher isn’t used on one purchase, the remaining balance usually rolls over for future use.
- Vouchers can provide more flexibility than coupons and promo codes and are excellent for repeat shoppers or gift recipients.

When to Use Each: Practical Scenarios
Choose Coupons When:
- You want to save on common household or grocery items—especially during weekly shopping trips.
- You like the option to use discounts in-store and enjoy the familiarity of paper or digital coupons.
- You’re looking for automatic or easy-to-redeem discounts without entering long codes.
Use Promo Codes When:
- Shopping online for specific, limited-time deals, like fashion, home goods, travel, or beauty products.
- You want to stack offers, such as promo codes on top of cash back, when allowed, for even greater savings (as outlined in our coupon stacking guide).
- Chasing flash sales, first-order bonuses, or exclusive influencer campaigns.
Redeem Vouchers When:
- You have a gift card, brand credit, or loyalty program payout you want to apply flexibly.
- You want the option to use partial value now and save the rest for future purchases.
- Your goal is simplicity—a single code acting as payment without worrying about exclusions or eligibility requirements tied to the cart.

Common Questions: Promo Code, Coupon, and Voucher FAQ
What is the primary difference between a coupon and a promo code?
Coupons can be physical or digital and are widely used in-store and online, providing direct discounts. Promo codes are always digital, must be entered at checkout, and deliver time-sensitive online deals or additional benefits like cashback.
Do vouchers always work like gift cards?
Most vouchers function very similarly to gift cards, carrying a set value that can be spent over multiple purchases. However, always verify the voucher’s terms, as some may be limited to specific categories or time frames.
Can you combine promo codes and coupons?
Most retailers don’t allow simultaneous use of multiple codes. However, you can often use a code in one purchase and a voucher or coupon for another, or use a code alongside sitewide promotions or cashback. For advanced strategies, see how to make promo codes work at every store.
Where do I find the best and most reliable codes?
Trusted sites like Giving Assistant collect codes from thousands of stores, verify their validity, and keep them up to date so you don’t waste time with expired or fake offers.
What restrictions should I watch for?
Common restrictions include minimum purchase amounts, category exclusions (such as no discounts on sale items), and one-time use per customer. Vouchers are often more flexible but always check for expiration dates and applicable items.
