Ask!

Many do not advertise it but will do a bulk discount if you ask. I'm pretty certain Namecheap is one of them (if you have more than 50 I think).

Contacted a help person @namecheap. when I asked for 50+ domains, was told, there is no bulk discount other than the current SOPASuck type deal. The current SOPASucks is limited to 10 domains.

I Wish there was a bulk discount. Pity namecheap couldn't come up with tiered bulk domain transferring pricing.

yeah with almost 100 domains, I'd love to move them all at once and save some coin.
