Sub 400 for the frame is impressive. Ali shows me 470 + shipping right now, did you negotiate or you were just seeing a lower price at the time? (Ali also changes offers & prices per geography).
I forgot to mention the included shipping and tax, so it was about $500 USD, plus I ordered a spared derailleur hanger which I highly recommend. I've had no problems with the hanger, but it's mounted with 1 bolt and I've heard other owners complain regarding it's durability (in case your bike falls). Also I would ask if you could swap the seat post with one that uses a different saddle mount. The stock hardware uses a round-style clamp head which needs different hardware depending on the saddle rail shape (oval or round). I opted for an oval saddle clamp, but even with carbon paste applied it kept slipping. So I had to wrap my saddle rails with gaffer tape to keep them from slipping.
This particular TFSA store (I guess there are multiple) has it, but you can look around:
