Adorama via eBay offers the refurbished Canon EF-S 18-200mm f/3.5-5.6 IS Zoom Lens, model no. 2752B002, for $279.99 with free shipping. That's tied with our August mention and the lowest total price we could find by $128. It features an optical image stabilizer and both front and rear lens caps.

It's not clear if a 90-day Adorama warranty or 1-year Canon warranty applies. (The product page notes both.)
