Ive seen it there in some of the chicken mixes but im not sure if they have just lavander buds. They ate closed today but monday they would happily answer you via phone facebook or email.
Call. They are friendly and helpful.
I'm pretty sure they don't carry just Lavender buds. I Googled it and found some craft stores that carry it as well as Amazon shopping.
