Update: Sold out
Still haven’t made the transition to LED? Amazon will sell you a 6-pack of highly rated TaoTronics soft white bulbs for just $11 right now with promo code HL63ISTM. These put out the brightness equivalent of a 60W incandescent, but with only 9W of electricity each. Plus, many local utility companies offer rebates when you buy these things, so they should pay for themselves in short order.
Note: These bulbs aren’t dimmable, which isn’t surprising at this price, but just make sure you’re aware.
