Got a flyer in the mail and have ordered from both my and my Mom's address (both Duke customers.) There is a zip code validation, but may work in other areas.
Bulbs I've gotten are all 2700K and none DOA. Shipping took less than a week for me.
$2/ea dimmable 65w BR30 or BR40
$10 for 6-pack of dimmable 65w BR30
$10 for 6-pack of dimmable 100w A21
$5 for 6-pack dimmable 60w decorator globe vanity light bulbs
$10 for 6-pack of dimmable 40w candelabra style bulbs
I looked around and couldn't find a better deal on BR30 or the globe bulbs.
Spend $15 to get $5 flat rate shipping.
The only catch is that you're limited to 15 bulbs per "customer." I used the same name and billing info for my 2 orders that shipped to 2 different addresses with no problems.
