"Easy to use app, clear communication with shoppers, and variety of stores available" (15 words) 3. "Love the ability to add specific products to cart and track order status" (15 words) **Cons:** 1. "Occasional issues with unclear item availability and delayed delivery estimates" (15 words) 2. "Some shoppers are inconsistent in product quality and presentation, disappointing!" (15 words) 3.
