Got a free set from the Lego store in Singapore airport (birthday month)

I was walking in Singapore airport (Terminal 4), and I saw the Lego Store had a special offer where you could get a free gift during your birthday month. I went to ask the seller, expecting a free mini-figure or other, and he asked me to pick between 3 little bags (minifigures) and... this box lol I heard this set was a limited edition from last year, so maybe I got super lucky because they're trying to clear the stocks submitted by /u/jeannen [link] [comments]
