How's GS shopping in Taipei like?

Any Taiwanese GS fans here? Would appreciate your feedback. :)

Really interested in the SBGA 413 Shunbun and I have a trip to Taipei next month. Very keen on purchasing it there as I really like the experience of getting watches abroad!

Was just wondering 1) how liberal GS ADs/boutiques are there in terms of discounting, and 2) how easy is it to find a Shunbun there.

Just to share, in the country that I'm currently residing at, I can get the said watch for USD5k after discounts. Hoping I can get the same or an even better deal in Taipei.

Thanks!
