I'm constantly doing this and yet I still never learn. I go to the store and see something I like but don't want to part with my money. I then decide that I do want it and go back to the store a few weeks later only to find that the item is no longer available.
This happened to me a few months ago with a pair of Express jeans and just today with a piece of artwork at HomeGoods.
If you see this print somewhere let me know. (Yes, I'm one of those people that takes pictures of things I like at the store.)
I did score this lamp though. The stacked ball lamp may no longer be trendy but I love it and that's all that matters.
