A shopping portal is an online platform operated by an airline, hotel program, credit card issuer or third party that rewards members with bonus points, miles or cash back when they click through to a participating retailer and make a purchase. The rewards are earned on top of any points or miles you already earn by paying with a travel rewards credit card, making every qualifying purchase an opportunity to double your return. Major airline and credit card portals partner with hundreds to over 1,200 retailers, covering everything from everyday essentials to large electronics.
TL;DR / Key takeaways
- What it is: A shopping portal is an intermediary website that tracks your purchase at a partner retailer and credits your loyalty account with bonus points, miles or cash back in exchange for the referral commission the retailer pays the portal.
- Double dipping: Portal earnings stack with your rewards credit card, so you earn from both sources on the same purchase.
- Earning rates vary widely: Rates typically range from 1 point or mile per dollar spent to 25 or more points or miles per dollar spent during promotions.
- Compare before you buy: Use a portal aggregator like Cashback Monitor or Evreward to find the best rate for your specific retailer before each purchase.
- Rule of thumb: Always start at the portal, not the retailer’s website directly. One missed click-through means missed rewards on purchases you were making anyway.
How a shopping portal works
Shopping portals earn you bonus rewards through a simple affiliate mechanism. When you click from a portal to a retailer’s site, a cookie is placed in your browser that tracks any purchase you complete. The retailer pays the portal a commission for the referral, and the portal passes a portion of that commission back to you as points, miles or cash back.
Here is the step-by-step flow for a typical portal transaction:
- Log in to your preferred portal using your loyalty program credentials.
- Search for the retailer where you plan to shop.
- Click through to the retailer’s site from within the portal. Do not navigate directly to the retailer’s homepage before completing this step.
- Shop and check out as you normally would.
- Bonus rewards will post to your account, typically within a few days to a few weeks, depending on the portal.
A few technical notes that affect whether your rewards post: cookies must be enabled in your browser, incognito or private browsing mode blocks tracking and will prevent earnings, and you should only use promo codes listed on the portal itself. Using an outside coupon code can void your portal rewards for that purchase.
Types of shopping portals
Three main categories of portals exist, each tied to a different type of loyalty program. Knowing which type aligns with your goals helps you direct your spending to the right platform.
| Portal type | Examples | Reward currency | Best for |
|---|---|---|---|
| Airline loyalty | AAdvantage eShopping (1,200-plus retailers), MileagePlus Shopping (1,100-plus retailers), SkyMiles Shopping (1,000-plus stores), Rapid Rewards Shopping (1,100-plus retailers) | Airline points or miles (some portals also award elite-qualifying credits) | Travelers focused on a specific frequent flyer program; AAdvantage eShopping also awards Loyalty Points toward elite status |
| Credit card issuer | Shop Through Chase (500+ retailers) | Transferable points redeemable for travel or transferable to airline and hotel partners | Travelers who prefer flexible rewards over program-specific points or miles |
| Third-party cash back | Rakuten (3,500-plus retailers) | Cash back or, if you hold an eligible card, transferable Membership Rewards points or Bilt Points at a 1:1 ratio | Shoppers who want the highest per-dollar return regardless of loyalty program, or those who want to diversify across programs |
Note that some portals, such as Capital One Shopping, award credits redeemable for gift cards rather than transferable points or miles. That distinction matters if earning flexible rewards is your primary goal.
How to maximize shopping portal earnings
Earning rates for the same retailer can differ significantly across portals and change daily or even hourly. The single most effective habit is checking a shopping portal aggregator before every purchase rather than defaulting to one portal.
A portal aggregator collects and displays current earning rates across dozens of portals for any given retailer. You search the merchant name and see, side by side, what each portal is currently offering. Popular aggregators include Cashback Monitor and Evreward. Both are free and take seconds to use.
Beyond comparison shopping, a few other tactics can meaningfully increase your earnings:
- Stack portal earnings with issuer offers. Programs like Amex Offers and Chase Offers can be activated on your card separately and often apply to the same purchase, creating a third layer of rewards on top of your portal and credit card earnings. Terms apply; enrollment required for Amex Offers. You must also activate the Chase offers.
- Watch for portal-wide spending bonuses. Many airline portals run promotions, particularly around holidays, that award a lump sum of bonus points or miles after you hit a cumulative spending threshold across any participating retailers. These can push the effective earn rate well above the standard per-dollar offer.
- Consider which currency you actually need. If a third-party portal offers more cash back for a purchase than your airline portal offers in miles, it may be worth running the math using TPG’s monthly points valuations to determine which option delivers more value.
- Use browser extensions to keep the habit automatic. All major portals offer Chrome or Safari extensions that pop up when you land on a participating site. Activating rewards takes one click rather than a separate site visit.
