Would one ship faster than another? Is shipping more expensive on one of them?

I'm considering getting Japanese glass GO stones, both sites seem to have it at a different price:
S225 glass stones from kiseido.com for $120
SJ030 glass stones from yutopian.com for $89

So I was wondering if shipping time or something else is different. I could not get any information on the stones themselves, so I'm now asking whether purchasing process and shipping is different. Any advice is appreciated.

Unless things have changed they are both shipped by the same people from the same place.

2019.07.05: Unnecessary update: Yutopian is officially out of the go equipment business. I do not know what has happened to Yutopian’s partnership with Kiseido or the status of Kiseido’s inventory. However, my recent emails to Kiseido have gone unanswered.

Kiseido and Yutopian are still shipping books, but not equipment.
