I hate shopping for clothes. (Books are a very different matter.)
I hate it so much that my current clothes have to be literally falling to pieces before I will rouse myself to go hunter-gathering for more. Not only that, I'm picky. I only like certain colours (nothing bright, nothing pastel -- only browns, green, yellows, and other earth colours) and plain styles.
Now, this multiple purchase techniques doesn't always work. Shops often have only one or maybe two items of a given style and size. But, with the advent of the Web, this is no longer a problem. Buy the one successfully hunted down, go home, log onto the shop's website, type in the product code, buy several more, get them delivered to the door. I've used this technique successfully, too.
