VistaPrint offers a Custom Case for Apple iPhone 4, 4S, or 5 for $9.99 plus around $5 for shipping. That's $19 under the lowest total price we could find for a similar custom iPhone case sold elsewhere, although we saw these cases for a few cents less last week. You can add text to existing designs, or upload your own photo.

Note: Items ordered with standard shipping are not guaranteed to arrive by Christmas. You can pay an extra $3.15 to upgrade to priority shipping and guarantee 7-day shipping.
