As one of its daily deals, iTech Deals offers this Generic Lightning to Micro USB Adapter 2-Pack for $4.99 with free shipping. That beats our January mention (which only included one adapter) and the lowest total price we could find. (It's a current price low for this quantity by $3.) It allows you to use a micro-USB charger or cable to charge and sync Apple devices with a Lightning port. Deal ends today.

Update: As a reader found, sheena55 via eBay offers it for $1.99 with free shipping. Note that this item ships from China, so expect it to take two to three weeks to arrive.
