I used the scan option to put in a few groceries that we buy often and still had the packages for currently in the house, what a GREAT feature. It was quick and easy to use and found everything I scanned in the pantry. There were a couple of items that I had a hard time finding, like the Red Bell Pepper, I didn't realize that I had to go to Pepper and find the variety in the list. I was also a tad confused with the weight vs. package option as I thought I could put in 28 oz in weight, which is only in pounds, but there is an option to change the package size under canned, bagged and boxed items. Now that I know this it will be easier to change things next time I go shopping! And because I have no added a ton of stuff to my favorites, entering them in next time will be much faster, although I am hoping they soon add a "search" option to the favorites section.
I loved how I was able to make two separate lists, one for Costco and one for the Commissary (military grocery store). When I was unable to find something at Costco I was able to quickly move it from one list to the other, as I went to Costco first and then headed to the Commissary to finish up. I also loved the fact that as I checked things off my list they moved to the bottom of the page so I didn't have to scroll through them when seeing what else I needed to shop for.
All in all shopping with Grocery IQ rather than a paper an pen list was a great experience. I still need to learn how to move the aisles around to match my store, but I figured I would save that for my next shopping trip. Looking forward to using this program over and over and over again.
