For today only, you can get a code on Facebook for a free TinyPrints Halloween greeting card with free shipping if you have it sent to your own house. If you try to ship it elsewhere, you'll have to pay $.44 for a stamp. That's always perplexed me. Why is it free to ship something to my house but not others?
While we're on the subject, since when did Halloween greeting cards become a thing? Not that I'm complaining. I was an instant convert as soon as I saw the “Have a Corny Halloween” card.
