It's the classic battle of the sexes: You send your husband to buy frozen peas. He returns with nothing but Mountain Dew and toothpicks.
Here to help in your quest for inter-household supermarket success is Grocery iQ, a website and smartphone app for creating and using shared shopping lists.
Upon signing up for a free account, you can begin building your list, either by entering items manually or by scanning bar codes with the handy iPhone, iPad or Android apps. Save common purchases as favorites (for easy reordering) and browse the coupon section to save a few bucks. Plus, since Grocery iQ works across all devices, items you add on your computer will automatically sync to your phone, and vice versa.
The best part, however, is the ability to share with others. Invite family members to edit a common list or just email yours for viewing so as not to end up with questionable additions.
We recently sent a good-natured male friend to market with our joint list in hand (well, on phone) and he found the process of finding items--Grocery iQ sorts by aisle--and checking off purchases to be totally intuitive.
Now if only we could work on his dietary habits.
