Just a reminder everyone.
Try to wrap your gift, then place it in a shipping box, so your buddy can put a wrapped gift under the tree instead of a plain USPS postal box.
When you send me your tracking number, also tell me if the inner gift is wrapped, so I can let your buddy know if they can open the shipping box. And let me know if you have any additional instructions for your buddy.
In general, if a card is included, open the card last, as that might give clues as to your buddy or explain some of the gifts.
