Aside from the fact that I basically had to start over, because none of my saved information was available, (my lists, previously purchased items, etc) I found MarketStreet much easier to use. Deals are easy to see as you shop for items and the coupons are right there with the item so you can purchase easily without a lot of back and forth. My biggest gripe is that you still have to choose substitutions or no substitution on EACH item! Personally, I find it highly annoying, because I already spent time making my selections. It would be nice to choose whether to allow a substitution or not at the time an item is selected, saving customers extra time later.
