True, the picking quality is a big factor for the experience. Especially when it’s about shopping for ingredients for a meal. We try to improve this by placing the order on behalf of the customer, so we can optimize the product selection for the cooking experience and have the option to guide the pickers with comments/chat towards the most appropriate products or suitable substitutes if something is out of stock.
Besides that we are considering to give the user an option to simply export the optimized shopping list, so it can be used for offline shopping. We got this a few times as a feature request from users who like to shop the ingredients themselves, but still like a service which provides them with personalized suggestions each week and generates a combined shopping list.
