That's a good question. The price of postage for a Christmas card depends on the type of card, the weight of the card, and the destination of the card. Generally, a standard Christmas card weighing up to 1 ounce would cost 58 cents to send domestically in the United States, while heavier or oversized cards could cost more. If you're sending a card internationally, the cost would be higher, typically ranging from $1.30 to $4.70 depending on the destination. It's always best to check with your local post office for exact postage rates.
