Only positive is that it's convenient and saves a trip to the store. When looking for items they do not include any store brands, which are usually cheaper. Basic items do not always need to be brand named but this does not show you them, only thr brand names which cost more. From past experience if I do not pay extra for express, the order is almost always delayed way past the expected time. Items that are out of stock are always replaced with higher priced items, sometimes a few dollars higher
