Is this what you're referring to for Amazon Prime? https://www.amazon.com/ALBUM-Version-1-BLACKPINK/dp/B08GFZKMNR/ref=redir_mobile_desktop?ie=UTF8&aaxitk=81N7Ih9YM.KAfhKpPpXqMQ&hsa_cr_id=9728492030101&ref_=sbx_be_s_sparkle_mcd_asin_2

From your post description, both options sound like the default content within the album but you also mentioned the group poster, so that's likely the reason for the different. I hope that I answered your question. It can be tricky tracking different sellers who each have their own prices and benefits.
