We have recently introduced Sale prices to select stores in the Dumpling app.
Items that are on sale can be identified by the yellow strikeout through the original price with the sale prices listed next to it.
Stores that have Sale items will also have a category in the Browse view, dedicated to all items on sale.
At this time:
We have sale items for Kroger, Albertsons, Whole Foods, Food 4 Less, Fred Meyer, Fry's, Harris Teeter, King Soopers, QFC, Ralphs, Smith's Food and Drug, ACME, Haggen, Jewel Osco, Lucky, Randalls, Safeway, Shaws, Tom Thumb and Vons.
The sale price is only shown in the app when the sale is active. Once the sale is over in the store, the price will go back to normal.
The sale price is still just an estimate, and the actual price can vary by store and region.
