One of them lowers the price of dot coms to $2.49, the other one to $2.95 and the third to $4. Not sure about the first two but the third coupon works for up to three domains.

Also, I’m not sure whether or not they work for all countries or only for customers from the US/Canada, didn’t try any of them myself.

Here’s the $2.49 coupon:

Here’s the $2.95 coupon:
