Turmeric or Tumeric?

I have labmates from Turkey and Iran, and the other day they were asking me where they could find turmeric. They said they were having trouble finding it at their local supermarkets.

 

I took this photo as proof that a) it's commonly sold in most American supermarkets (this was in Wegmans, but I've seen it elsewhere) and b) lots of Americans pronounce 'turmeric' without the first 'r'.
