The Special Boxes are now available in Pokemon Go, and players can choose between three boxes – Special, Great and Ultra – each featuring different items and with a different value.
The boxes have been live since February 23, and today as confirmed by Niantic support (email confirmation), the sale will end on March 11, at 1:00 PST.
The email by Niantic Support:
Thanks for spending your valuable time to write us.
I do understand that you wish to know of the Special Boxes in the Shop. I would inform that the Special Boxes had been available from Friday afternoon (2/23) PST and would be there till Saturday (3/11) at 1:00 PST.
This would answer your inquiry. If you have any further inquiries, I would be happy to answer.
Best regards, Dana Niantic Support”
So, there is still a plenty of time for some to get their Box(es), and I recommend to get the Ultra Box for 1480 PokeCoins.
