The issue is the sheer number of apps. So Consumer Reports ShopSmart has figured out which ones make saving easiest and most accessible.
1. Price Check by Amazon. It lets you scan a product's bar code, snap a photo, OR just say its name to see whether Amazon sells it for a lower price.
2. RedLaser was one of the first price comparison apps and Consumer Reports says it's still the gold standard. Plus, it helps you find deals and coupons for retailers - and store digital versions of loyalty cards.
3. ScanLife lets you price compare and share prices with fellow scanners. The app has a live feed that shows prices that other people have scanned.
4. ShopSavvy is what Consumer Reports calls the granddaddy price-comparison app. It now features user reviews and product videos.
5. Smoopa is all about sharing prices that users find. Stores are graded by how often they return the lowest prices among Smoopa users. If you find an in-store price that's better than what's available online - Smoopa may offer you a special reward like a gift card to a store like Amazon or Walmart.
