It's your call, but I think you are doing the right thing refunding the difference. Besides, for a paltry sum, you probably feel better and I know that the recipient will really enjoy the fact that he dealt with a good seller. Win-win in my view.
OK, what's the protocol?
So, you provide an honest quote for shipping on an item and the actual cost is less. Are you:
A) Obligated to provide an unsolicited refund regardless of the overage
B) Obligated to provide a refund only if solicited regardless of the overage
C) Obligated to provide an unsolicited refund only if over a certain amount.
D) Obligated to provide a refund only if solicited AND over a certain amount
E) Never obligated to provide a refund under any circumstances
And by obligated, I mean obligated by the rules of decorum established here or by the values of a gentlemen whichever are more conservative.
