CellularFactory offers this USB Travel Charger Power Adapter, in White for $1.99. Bag free shipping via coupon code "F2EIST". That's tied with our August mention and $1 under the lowest total price we could find for a comparable adapter elsewhere. (For further comparison, we saw a similar charger for $1 less last month, since expired.) This unit features two prongs plus a USB port. Coupon expires November 18.
