Wikibuy is described as 'While you shop on Amazon, Wikibuy evaluates other sellers like Walmart, Target, eBay, Jet, and others you might find with a Google search'. There are more than 50 alternatives to Wikibuy for a variety of platforms, including Online / Web-based, Windows, iPhone, Google Chrome and Mac. The best alternative is Honey, which is free. Other great apps like Wikibuy are RetailMenot (Free), Price Snoop (Free), Invisible Hand (Free) and Prisync (Paid).
InvisibleHand discreetly notifies you if the product or flight you’re shopping for is available more cheaply from another retailer or travel site. The notification provides a convenient link straight to the relevant page on the competing website.
Dealspotr is like Wikipedia for deals. We have 4x more working promo codes than any other coupon site. Tired of expired coupons? Dealspotr is community-driven and we show screenshots demonstrating how every code in our database works.
LuckyCoupon automatically tries popular coupons on every checkout for you. Unlike other coupon extensions like Honey, LuckyCoupon also tries the most common couponcodes to get you a discount. THANKYOU, 20OFF, WELCOME. You name it.
