I *love* Target & Walgreen's when I go over to Buffalo across the Peace Bridge.
I also like the experience of passing through customs. It's an exhilerating experience heading into the U.S. when they have the K-9 Cops walking up and down the line of cars sniffing for drugs or perhaps explosives. Driving up to the window wondering what sort of demeanor the customs officer will face you with and if you can make them laugh, it feels like the keys to the kingdom as they forward you onward.
When I go over the border, I like to have lunch at Johnny Rockets at the Walden Galleria Mall. They sing and dance during your dinner when R-E-S-P-E-C-T plays and their Original hamburger is delicious and sinful. You don't want to eat that burger every day for sure. It comes with "American" cheese (here, it's just "cheese").
In Target, my eyes scan everything for every potential item that we don't have in Canada that I might want to take home. Yesterday I bought coconut hair conditioner for 87 cents! Then later I go to Wegman's (wow, that's a "meal market" instead of a grocery store) and bought 3 cases of Diet Cherry Coke to take home. We don't have that in Canada; only Cherry Coke. The only problem I have with Target is that there's no shopping music to listen to and instead you can hear all the associates radioing each other on their headsets.
Making it back into Canada is interesting as well. I once had my car turned inside out when officers were searching for all the purchases my mother and I made so they could take us inside and come up with the final tally of what we spent. They confiscated DHEA that my mom bought at GNC (turns out it's illegal here). Very interesting.
