So I placed an order last night so I could get the sample bag. I also noticed I had left my birthday gift in my cart from, like, June (which means I was a good girl and hadn't made an online order since then).
BUT LATER: I looked at my purchase history and saw that I had apparently picked up my birthday gift in store, among other purchases. (So I wasn't a good girl after all, just a good girl online.)
Will Sephora get down on my butt for doubling up the birthday gift? I had totally forgotten all about it, honestly, but I know they can be jerks about these things sometimes.
