I just did this shop....matched up only 5 of the 50 items. When I input it, it told me that another 29 had been found by other shoppers. I spent over 2 hours in the store doing this and was very frustrated by the end....
Was I really that far off? I am sure that some of those 29 weren't there.
I stopped doing these because they want you to be discreet but when you come across an item you have no idea what it is, you gotta ask for help from an associate. Then the associate wants to know what's it used for. Too much of a hassel.
