Quoted from stevef:US$ 0.19 for one bulb- sorry!
In UK cheapest bulbs are $0.45
You're paying 37 cents a bulb if you just buy 100 though.
Curious to see what you get. Imo big difference in bukbs good enough to resell and bulbs people who want to go cheap on will use. These may work well for you, but not resellable for us or maybe comment for example.
