During the period between yesterday (April 26th) and May 9th, Club MG members who register the special ticket from MG Wing Gundam on the Club MG's website will receive 4 points; registration of other Club MG corresponding MG kits will receive 2 points. Without the campaign, only 1 point will be awarded to each kit.
On the other hand, extra benefits are planned for Club MG members with 20 points and above. Those with 20 points in Club MG by May 31st will receive a special Gunpla 30th Anniversary sticker; those with 40 points and above can get the same special Gunpla 30th Anniversary sticker, plus a special nipper. Those who are eligible must sign up in order to receive the prizes.
Club MG is a special fan club set up by Bandai on January 1st for MG kit builders and collectors. One can receive points by entering the special ticket number from MG kits purchased onto Club MG's website. Different points will entitle members to different rankings and the eligibility to receive certain rewards from Bandai, for example participation in Bandai Hobby Center Tour announced in mid February. More benefits will be announced in the future for sure.
