I am lucky that my church sells it before the holidays. Do you have a Ukrainian church in your area? You could call them.... they usually know where to get the wheat and poppy seeds as well.

If not, a natural food store might carry the items.

Veselych Sviat (Happy Holidays)
Chrystos Razdiatsia - Slavite Yoho (Christ is Born - Praise Him) This is the traditional greeting

Some of the Ukrainian sounds just don't translate well! :)
