Saving money online is not about clicking every coupon or chasing every deal. It is about checking the right places before you spend, comparing the full cost and avoiding purchases you did not plan to make. The websites below cover several different jobs: finding discounts, comparing prices, earning cash back and accessing free resources.

Coupon and deal websites

These services can help locate promo codes, sales and community-shared offers. Always check the final checkout price because a coupon may not be valid for every item.

• RetailMeNot — coupon codes and cash-back offers.
• Coupons.com — printable and digital grocery and retail coupons.
• Slickdeals — community-submitted deals and deal alerts.
• DealNews — curated deals across product categories.
• Brad’s Deals — hand-picked discounts and shopping offers.
• The Krazy Coupon Lady — grocery and household coupon strategies.
• Woot — limited-time deals across assorted categories.
• Groupon — local experiences and service offers; compare restrictions carefully.

Cash-back and rewards platforms

Cash back is usually funded by retailer commissions and may require tracking, activation or a waiting period. Treat rewards as a bonus—not a reason to buy something you do not need.

• Rakuten — cash back at participating retailers.
• Ibotta — grocery and retail offers, often requiring receipt or account-linked verification.
• Fetch — points from eligible receipts and purchases.
• TopCashback — cash-back shopping portal.
• Shopkick — rewards for eligible shopping activities.
• MyPoints — points for eligible shopping and other activities.

Price comparison and shopping research

A low advertised price is not always the lowest total cost. Compare shipping, taxes, return policies, warranties and seller reputation before choosing.

• Google Shopping — compare listings from multiple retailers.
• CamelCamelCamel — track Amazon price history.
• Keepa — price history and alerts for Amazon listings.
• Price.com — price comparison, coupons and cash-back options.
• eBay — compare new, used and refurbished listings, checking seller ratings.

Free resources that can reduce everyday costs

• USA.gov Benefits — official starting point for checking government benefit programs.
• 211 — connect with local help for housing, utilities, food and other essentials.
• Lifeline — information about eligible phone and internet discounts.
• Benefits.gov — benefit information and eligibility guidance where available.
• Freecycle — local groups for giving away and finding reusable items.

How to use these sites without wasting money

Start with a purchase you already planned. Search for the product, compare at least two sellers, check the return policy, then test a coupon. If cash back is offered, read the tracking and payout rules before relying on it. For groceries, compare unit prices and store-brand alternatives instead of focusing only on the coupon value.

Be cautious with browser extensions and deal sites that request broad permissions or personal information. Use official retailer apps for account-specific offers, avoid suspicious downloads, and never pay a fee just to access a supposed coupon code.

The real savings test

A deal only saves money when it lowers the cost of something you genuinely needed. A 40 percent discount on an unplanned purchase is still spending. Pick two or three tools that fit your habits, use them consistently and track the amount you actually kept.
