I wouldn't call the Milwaukee angled drill a light weight tool - it has some good heft to it and wouldn't surprise me that it would be a couple pounds shipping...
OK, just had to put this to rest for my own sake: Amazon lists the Milwaukee 3/8" close-quarter drill at 3.5 lbs (they also call it light weight, btw); Shipping via USPS from Oregon to New York would be $7.87 via Parcel Post and $10.35 via Priority Mail. Add in a couple bucks for insurance and you're not too far off the $17. (I'm not saying it's not padded but it's not waaaaay out of line - and if a higher volume seller has to buy any shipping supplies he has to make up that cost.)
