If you keep chasing coupons, your gonna end up with domains all over the place, and then you'll be paying full price for renewal anyways. Best to stick with one, imo
check out netfirms for example$0.99 is well under cost. Those coupons are usually limited to 1 per person and it's understood you will be paying full price next year, unless you transfer out.
Registrars selling at $9 are not even making a $1 profit after processing & credit card fees.
It's a volume business.
If you buy great domains, paying $10 shouldn't be a cause for concern.
Don't worry about that, after the 1st year, you can transfer to another registrar with transfer coupons to get the discount price on that new registrar, and the next 2nd year you then transfer again to another registrar with transfer coupons also, repeat this againEven if you get a coupon, the price is only for the first year. From the next year onward, you will have to pay the full price anyways. Better buy good domains even if not on a discounted price
