Is halopets.com Safe?

I signed up for their email newsletter in Sept 2010 and have not received any spam. I do received $2 off coupons. One cat loves their dry food, but the others don't care for it. No one likes the small pkg of treats. Their food is rated high for it's quality and balance and I tried it because it's suppose to help with cat skin allergies. Since that cat won't eat the food, I don't know if it works. I have had no problems with the site, email or printing of the coupons. *****

I inherited about two cases of Halo cat food from a friend who had no need for it, and my cat has gone absolutely nuts over this stuff (Spot's Stew for Cats, Scrumptious Salmon Recipe). With regular, store bought brands, he can take it or leave it, and he usually leaves it. With this stuff, he literally licks the bowl clean every time. Although I had never heard of the brand before, my cat will probably insist that I purchase more very soon.
