Currently I use ShopNotes 1.1 as a shopping list application. Anyone know of an app that's a shopping list app, but also lets you save the price that you paid for sale items? Am looking around for an App that does this so I can remember where I got the best deals. EDIT: I found and am now reading this nice article on the topic from MacWorld (http://www.macworld.com/article/136247/2008/10/iphonegrocery.html) , although any personal experience/recommendation would be welcome.
I previously used Grocery IQ and I just added prices manually on that app but it didn't do any calculations which is a bummer. Prices do change very often though so what I do is just get the prices of the stuff I regularly buy (eggs, fruits, etc), add up the total bill for my normal purchase for each store and just stick with that store for everything.
