It is so funny that you would post this query, because it happens to me all of the time! I live an hour outside of Mpls/St. Paul, so when I head down to "the Cities", I'm super excited to shop but often return empty handed only to find the perfect item the next day at the local mall...a strange phenomenon. I've relegated myself to just enjoying the sights, sounds, and awesome restaurants when I go to the Cities and not planning any specific destination shopping. If should happen upon that perfect thing, that's a bonus
Congrats on not shopping for two months...wow! I can see why you would worry that it has made you incredibly picky, but I think that is a good thing because when you do buy something it will be the perfect item (do not show those sandals from Lamb's Ear again unless they are on your feet ) and will have been worth the wait. When I go on buying "binges", or purchasing items on a very regular basis I find myself not being as considerate of what I need/really want, maybe not being as particular to my own style as I should. Hmm...I'll be interested to hear what transpires on your trip.
PS enjoy the street tacos and music!
