I really like shopping once I reach my destination. And I find that I'm more likely to spend more on an item if I find it on vacation. Sometimes this is good, sometimes bad. I have some items from my two month trip to Europe back in 1990 that *still* get worn. A few items from that trip have worn out, and I miss them. Sadly, a few items were mistakes that never got the wear they deserved.
I don't know where you usually travel, but I feel this is a good time to share some advice with everyone. If the shop owner offers you some wine, which of course has been homemade by his family for generations (so how can you refuse?), be careful. Before long, you may be tipsy and buying out the store. Your friend with the wine will inevitably take you to another wonderful shop that happens to be owned by his friend after he sells you more stuff that you don't really need, and the cycle continues. Eventually, you will have to figure out how to get those two large Persian carpets onto the airplane home. And you will be heading to the outdoor market to buy a larger suitcase than the one you came with, just to fit the rest of your goodies.
