Itzys not shy signed albums

I just bought two of the itzys not shy signed albums, and im not sure if the price i paid is worth it. Is was 35€ for both of the albums (yunas and yejis signatures) +the seller said he will give me some free official photocards. They were the mwave ones that was sold back in 2020 when the album came out. The signature is on the poster/lyric paper. I think that this was a pretty good deal, but i didnt find any of these in ebay etc. so if any of u knows about the prices of theses signed pieces (since these are my first signed ones) that would help alot💕 (EDIT): The albums were 20€ each but the seller gave me a 5€ discount since i bought both!!
