I bought software from the website aislebyaisle.com, which provides an access to their grocery shop. I paid $25 for unlimited access. You need to build your own shop at which you usually buy goods. Then you create your grocery list, choose products and prices. I am not satisfied with software, because I have some technical problems. I wasted a lot of time and money to build my store, which never worked. The seller refused to refund money. Really disappointed with seller’s attitude and services.
