Whenever I complete a Google Opinion Awards survey, I get reminded that the credit will expire in a year.
Except I'm quite sure that I've accumulated credit for much longer than a year. Lately I spent most of it on a book, but I was wondering if anyone here actually has had their credit expire?
Does anyone know what the actual ruling of this is? For example, perhaps if you don't change your balance in a year (up or down) then it expires?
This. That appears to be my observation anyway.
