In an urban setting, I pass stores all the time in my regular every day (walking) errands around town. So my in person shopping mostly looks like just popping in, and if there is something there I need, I tend to get it very quickly and move on, so it takes very very little time. It's scary how little time it can take! My last purchase was a colorful little bandanna I got at Urban outfitters for 4.99 (attached to my grocery store), on the way to buy milk.
About half of my shopping is online...this literally takes minutes...as we all know only too well. Like when Angie posted the Swann shoes, I went to the website and ordered them straight away...it took five minutes. For some reason they gave me free over night shipping, and by noon the next day I had them. The returns are easier too, I find...I have a UPS store and a post office just a couple of blocks away.
So if you add up all the time, maybe it's a couple of hours a week? But your post makes me think I might want to pay more attention to how much time I do spend. Shopping is just the way I move through the world :)...but I don't always buy things.
Interestingly enough, the last time I was at the Mall was when they were fixing my laptop and I had time just to "kill" shopping...it was way longer (hours) than I usually spend, aimlessly looking, and I actually got sick of shopping! It made realize how purposeful and steamlined most of my shopping habits have become.
I too go through bursts, when it's kind of consuming, literally, as in I purchase more, then it levels off...and I don't think about it. I also clean out my closets regularly and sell them at another store that is just blocks away too ( I usually give the credit to my kids to use)...or gift them to others or to charity, as I live in an old apartment with a very small closet. So I'm probably just trying to make myself feel better, but if it's any consolation, others benefit from what might seem like my time consuming obsession :).
Now if you ask how much time I think about clothes, or I spend recently on the YLF forum...do I have to count that too? That might be many more hours!
