Stumbled across this today...
Buy a Bosch PS40 (subcompact impact driver) kit, get a free PS20 (matching subcompact drill/driver) by mail.
Or you can buy a PS20 kit and get another PS 20 (driver only)
I've had my eye on this pair for a while; they've gotten great reviews because of their l-ion power, light weight, and compact size. The kit comes with 30 min charger and two batteries, I assume the free tool doesn't come with battery, but it doesn't really say.
This is at lowes in NE Ohio, don't know if it's everywhere or not. If you search their rebate center for tools, you can find it. (Doesn't seem to work to search rebate center for Bosch for some reason)
