Based on the ITZY amazon link they officially tweeted out, it was sold and fulfilled by Amazon.com for $27.19
The Twice Link you posted is sold and fulfilled by Atoz Merchant who is based in Korea and says it will be shipped from there as well. It also mentions including the Synnara Transparent photocard as a bonus. So I believe this link is Synnara selling on Amazon. It's best to just wait for the official tweet about the correct link since really anyone can sell on Amazon.
