The information I can find on Deutzia describes it as having fragrant flowers of up to two inches, blooming May through June. WildwoodSage describes this bush as having no discernible fragrance, and the pictures posted show that the blossoms are about the size of a dime. The photos I found of Deutzia Pink PomPon show much larger leaves than WildwoodSage's plant. I'm in zone 4b, and Friendship, NY appears to be in zone 5a, and my Flowering Almond is in full bloom right now. 5a would be on the northern edge of Deutzia's hardiness range, so it would be unlikely for it to bloom so early there.
I agree. Something also about the shape - I grew up with a Prunus glandulosa 'Rosea Plena' and it wasn't always a full very small shrub completely as Deutzia typically is. The timing that l6blue mentioned sets the 2 apart. Leaves are different width.

Take a look at the small leaves, lenticels on one of the stems and colour of the stem.
I'm not familiar with Prunus glandulosa, but Almond is Prunus dulcis, and this plant isn't that!
