You can go to www.usps.com and order most sizes of boxes for Priority Mail for free? They even have one box about the size of a shoebox that's flat-rate of $8.10. Doesn't make any difference what the weight is...feathers or lead, it's still the same cost. Different size boxes come in different quantities, but they're all free.
Don't wait too long to tell someone you love them.
