dealnews is always running on a tab in my browser. Thanks to them I got the following (prices no longer valid):

• External 10K mah external battery for $16 Prime

• 8 port gigabit switch for $23 Prime

• 3 Cyberpower UPS' for $80 Prime

• Many items via NewEgg + free shipping

• Many tools via Sears + same-day pickup

I just wish they were hiring sysadmins. (sad face)

For everyone else. I found this last year for $16 via a Dealnews.com coupon. It's currently $18 Prime.
