A few question about "A BEST"

[lastminute]

I bought my copy of A BEST off of eBay a few years ago. It came with the sleeve case and alternate cover so, I obviously assumed it was a first press copy, which is great. However, I have a few questions I hope you guys can help me figure out.

1. I noticed my copy also included a set of stickers along with a DOME TOUR flyer. The tour flyer makes sense, it is supposed to be included, but... I just realized I didn't know the album included stickers, which leads us to my first question, is the set of stickers supposed to be in there or the eBay seller just kindly added it? lol

2. I also noticed that next to the release date printed in both the sleeve case and the CD's back cover, there's a second date: 03.3.27 (actually, it says "03.3.27まで"). What does it mean? I really have no idea lmao I'm wondering, is it a 2003 pressing of the album? and, If so, did they still made copies with sleeve cases and alternate covers 2 years after the album's release?
