It seems like a few stores enforced limits-- one woman on FB said the security guard at their store said no one would be allowed to check out with a cart full of Lilly. But the stores were few and far between.
I was interested in the plus size line which was online only, so I didn't even have the benefit of even trying the store. Even though they will never come out and say it, Target was definitely trying to keep this line "exclusive." Anyone who actually thought it would last through May 31 was slightly deluding themselves. I do feel bad for the people who planned events around these items, like family photos or wedding registries, I saw some of that.
I do think it's interesting that this line and the Missoni line practically flew out of the stores and the website, but they couldn't give the stuff in the Neiman Marcus line from a couple years ago away. I didn't realize Lilly Pulitzer was that popular.
