The lowest-effort way to save money online is installing a browser extension that automatically finds and applies discounts at checkout. You shop normally — the extension handles the rest.

Rakuten activates automatically when you visit a supported retailer and earns you cashback on your purchase. It's the most reliable cashback extension available and works at thousands of stores.

Honey tests available coupon codes at checkout and applies the best one. It's particularly useful for clothing and electronics retailers where promo codes are common.

Capital One Shopping combines coupon codes with price comparison, alerting you if the same item is cheaper elsewhere. It doesn't require a Capital One account.

Install all three — they don't conflict with each other and cover different scenarios. The combined time investment is about five minutes.

Many "sale" prices aren't actually sales — retailers regularly inflate original prices to make discounts look larger than they are. Price tracking tools show you the actual price history so you can judge whether a deal is genuine.

CamelCamelCamel tracks Amazon price history for any product. Paste a product URL and see a chart of price changes over time. You can also set price drop alerts via email.

Keepa is a more detailed Amazon price tracker that shows price history across different sellers, including third-party marketplace sellers. The browser extension overlays price history charts directly on Amazon product pages.

For non-Amazon retailers, Google Shopping's price history feature (visible on some product searches) and the Honey extension's price history chart are useful alternatives.

Many retailers send discount emails to customers who add items to their cart but don't complete the purchase. This is a deliberate retention strategy — and you can use it intentionally.

Add the items you want to your cart, create an account if you haven't already (so the retailer has your email), and then leave without purchasing. Wait 24–48 hours. A significant number of retailers will send a discount code — typically 10–15% off — to encourage you to complete the purchase.

This works best with mid-sized retailers. Large retailers like Amazon rarely do this. Clothing, home goods, and subscription services are the most likely to send abandoned cart discounts.

The most effective savings strategy is layering multiple discounts on a single purchase. Here's a typical stack:

• Cashback credit card: 1.5–5% back on the purchase
• Cashback portal (Rakuten): 2–10% back depending on the retailer
• Coupon code (Honey): 5–20% off the purchase price
• Sale price: Whatever the retailer is offering

Combined, these layers can add up to 20–30% savings on a single purchase. The key is to apply them in the right order: activate the cashback portal first, then apply the coupon code at checkout, then pay with your cashback card.

Note: some retailers exclude cashback on already-discounted items. Check the cashback portal's terms for the specific retailer before assuming all layers will apply.

Travel pricing is dynamic — the same flight or hotel room can vary significantly in price based on when and how you search. A few reliable tactics:

Search in incognito mode. Some travel sites use cookies to detect repeat searches and may raise prices accordingly. Searching in a private/incognito window removes this variable.

Use Google Flights' price calendar. The calendar view shows the cheapest days to fly within a month. Shifting your travel dates by one or two days can save hundreds of dollars on flights.

Book hotels directly after finding them on aggregators. Many hotels offer a price match or lower rate if you book directly through their website rather than through Booking.com or Expedia. Call the hotel directly and ask.
