Adorama Camera via eBay offers the refurbished Canon EF 28-135mm f/3.5-5.6 IS USM Lens, model no. 2562A002, for $192 with free shipping. That's $77 under our April mention of a refurb and the lowest total price we've seen. (It' also $208 under the lowest total price we could find for a new unit today.) It features an image stabilizer, 20" minimum focusing distance, and more. A 90-day Adorama warranty applies.

Update: The price has increased to $219 with free shipping. Despite the increase, that's still a price low by $181.
