Oh man I have a doozy shipping horror story:
Ordered a bunch of stuff (Benefit Bo-Ing, the Balm Meet Matte, Nude 'Tude, Mary-Lou Manizer, How 'Bout Them Apples, Beauty Blenders) on April 23rd that came with 2-day free air shipping. April 26th I emailed about it not shipping out within the promised 2 days. Jenna was super helpful throughout this whole process by the way, she was great, the Birchbox warehouse was not. I had to email twice about it because it hadn't shipped out. Finally it did May 1st.
I check my tracking, and it says it was sent back to sender for a hazardous materials situation. I contact Jenna again, she says the Benefit Bo-Ing can't go on a plane, she orders everything for me again, with the Benefit taking the slow ground route. I finally get my order May 9th. I opened it all up and the Mary-Lou Manizer is broken. I contact again, Jenna sends me a new one. I get the replacement today and the Benefit finally showed up as well. Well the replacement Mary-Lou was also broken. At this point I'm like I'll just make do with these two broken Mary-Lou's I have now, and get a refund for it. So she refunds me for that.
In this whole process I accrued 300 sorry points, which wasn't bad, but I'm not inclined to order anything again anytime soon.
