For earning cash back on purchases
▪ Ebates is “arguably the best-known service of its kind.” It offers rebates of up to 40_percent on products you purchase through the site or app, which link to 2,000-plus retailers, many of them major. Every 90 days, your rebates arrive as a check or PayPal deposit. Ebates’ rebates often aren’t as generous as rivals’, though, so shop around.
▪ BeFrugal is similar to Ebates but has thousands more retail partners and often offers better deals. Besides paying out generous rebates, the service highlights daily deals and offers printable grocery and restaurant coupons.
▪ Paribus keeps track of purchases you make online, and whenever a price drops after the fact, the app contacts customer service at the relevant retailer to get you any refund you have due. Just know that the app needs access to your email box to locate your receipts.
