Panini Noob Recommendations

Hey! I just bought the 2026 World Cup sticker album/packs and it takes me back to my childhood! I wonder if could buy an older panini somewhere for decent value. 2006 or 2010 world cup would be a lot of fun. Would you recommend any specific sticker albums to buy? I’m open to Serie A. And are there any good deals out there? Should I get it via ebay? And what do I do if I find a really rare sticker? Thanks!
