The app provides a simple, intuitive interface to help you find the best product.
To start, simply enter a search term in the search box and wait for the search to finish. The products that match your criteria will be displayed in the list. You can filter the results by price, brand, category, etc. You can also sort the products in the list by price or by the date they were posted.
If you are interested in a specific product, you can view its photo and read its reviews and ratings. You can also add the product to your favorites list so you will be notified when its price falls below your threshold.
If you have some time, you can also scan the product's barcode to get more information about it.
