from a shopper ...
 
"It would be nice to have cards appropriate for the American Orthodox Christians. If you had cards for Orthodox Easter or Holy Pascha, that would be suitable for all nationalities that are celebrating."
 
The shopper will find these cards here tucked under the Easter category:
Holidays >> Easter >> Orthodox Easter / Pascha
 
This is reserved specially for cards that are unique to Orthodox Easter / Pascha ... not general "Easter" cards.  It will also serve as a catchall for all related cards (general and specific (relations, languages, etc.).
 
Why two Easters?  It's a calendar thing:
