Best Buy discounts a selection of Insignia LED Dimmable Lightbulbs, as listed below. Choose in-store pickup to avoid the $1.99 shipping charge. That ties our fall mention for the first two and puts each at least $2 and up to $5 less than the lowest shipped price we could find for similar bulbs elsewhere.

The deals:
- Insignia 40-watt Equivalent Dimmable A19 LED Light Bulb in Warm White (pictured) for $4.99
- Insignia 60-watt Equivalent Dimmable A19 LED Light Bulb in Warm White for $7.99
