Last June 17, 2014, it was announced on MathOverflow Meta that “established users” that “have actually made (and will hopefully continue to make) valuable contributions to this site” would be given gifts if they ask for them. I filled up the form and waited, but I wasn’t sure if they would give the gifts to someone outside the U.S.A.
The goods arrived yesterday. I got a mug, an XL-size T-shirt, and three stickers in a box that was a little too big for the goods. The commercial invoice states that it was sent last October 21, 2015. I was very surprised that it took only around 7 days to reach me. (Most packages sent to me from the U.S.A. take a few weeks to a few months to reach me.) The invoice states that the mug has a value of US$ 5, the T-shirt is worth US$ 3, and each sticker is worth US$ 0.25. Thanks, MathOverflow!
