optional naming suggestion: it looks like the other functions here begin with
"get", so the fact that this one does not makes it sound a little more like this
would let you toggle whether redeeming offers was allowed or not. No big deal to
leave it as-is, but you might consider adding a "get" prefix to the name for
consistency.

Maybe checkAllowRedeemOffers?
