I recently purchased some hosting through Mydomain.com and I have to say I'm a pretty happy customer so far. The service has been good for what I pay and I run multiple sites on the same host. I used the coupon "bargaincat.com" to get a low price at checkout and I my bill.
Thanks for the review on MyDomain.com hosting as I was looking for reviews on their hosting deals plus the coupon will be useful too.
