You must politely decline the card because its value is more than $100. 1 is incorrect because this is a clear violation of your company’s policy. 2 is incorrect as well. Donating the card to charity would require you to first accept the card. This is also a violation of your company’s policy. 3 is also incorrect. While this seems like a feasible idea, the card has a value of $500. In order to use just $100 of the card, you’d have to accept the card, which violates your company’s policy.
