Jihanpi's 3 freebies end today

I found out yesterday by chance when an ad played that it ends today. Yesterday, I rushed to get SMS verification and linked it, and the expiration date was shown as 2027/3/28. So, it might be that 'the right to get 3 freebies by SMS verification ends today,' but I'd be sad if it's wrong, so I got my 3 yesterday. If there's anyone who's been looking for a chance to use them and hasn't linked yet, it seems like a good idea to at least link them by the end of today. (Although I think it would be safer to complete the exchange if possible, there might be unexpected issues like no compatible vending machines nearby, or it being sold out because many people had the same idea…?)
