hi i’m new to collecting amiibo cards so please bare with me if i seem confused.

on friday (6 days ago) i purchased some series 2 and series 5 animal crossing amiibo cards from the nintendo website. i then purchases some more of series 2and4 yesterday.

today out of curiosity i google series 1 and im taken to nintendo site. (i think) on the site it has series 1, 3 and 4 available to purchase (they weren’t available yesterday) im just a bit confused and worried ive been scammed unless they restocked them. any ideas? thank you in advance :)
