I send Chocolate chip cookies to both my grandsons in college. ( one in Southern California and one in New York) Both have said that the care packages come in very good condition. We live in the San Francisco Bay Area. I send Chocolate chips, because they both request them.
I get the boxes from the post office. ( If it fits it ships, medium size) I make the cookies, place about 6 in small zip lock bags. ( I get about 6 bags per recipe) I then wrap each bag in bubble wrap. I line the box with bubble wrap and arrange the individual packages in the box, and top with a another sheet of bubble wrap. Seal and address! I usually use the 2 day mail. It costs about $ 10-11 dollars to send them.
Both boys are usually very happy to get their Care Packages!!!
