Dell Home, via its Member Purchase Program, offers the Dell 16GB Class 4 microSDHC Card for $7.59 with free shipping. That's the lowest price we could find by $6, although we saw it for $2 less with a $5 Dell gift card in August. It comes with an adapter.

Note: Dell's MPP is available to select groups, including students, government employees, military (active and retired), credit union members, and health care workers.
