AccXpress via eBay offers the OEM Apple 60-watt MagSafe Power Adapter for MacBook, model no. A1344, for $34.95 with free shipping. That's tied with last week's mention and the lowest total price we could find by $5. It's designed for the MacBook and 13" MacBook Pro.

Note that it ships in bulk packaging and does not include the AC extension cable wall charger.
