There are a few registars that will give you discounts for buying in bulk. I would think Domainsite, Godaddy. Especially Godaddys .infos. But if I were you buying 1000 I would stick to the more popular extensions of .com, .net, .org
GoDaddy: https://www.godaddy.com/gdshop/registrar/bulk/bulk.asp. If needed you can lower the costs by using a coupon, which are widely available on the web. Good luck!
Godaddy seems to not do domains in 1000s, but if you bought two batches of 500 it would cost $3.04 per/domain.
each .info domain name is $2.19 in godaddy so if you buy 1000 you must be something like $1 though im not sure
I know this isn't answering your question, im just wondering why you need 1000 domains. Are these going to be domains that you choose?
1,000 domains? big project there bud, I use dynadot for my 3 sites if your doing something big with 1,000 sites pm me and let me know =P
everything you try dont try Dynadot , dynadot is scam,,!they charge you more after you paid even for a simple privacy..if i were you would try Godaddy or Name.com
But godaddy selling at 6$ which way high as u people are saying it is just 1$ and stuff can someone breifly explain me..
