Can contextual bandit rewards be changed over time?

I am working on implementing a contextual bandit with Vowpal Wabbit for dynamic pricing where arms represent price margins. The cost/reward is determined by taking price – expected cost. Cost is not known initially so it is a prediction and has the…
