Package from Santa.com has been a sponsor of ours for four years now. I personally have not purchased their products.
However, in the time we have had them as sponsors I have never had a complaint and HAVE had some comment how good their services are.
That has not always been the case in the years we've had the site. In fact, I have had to let some some Santa letter folks go because of complaints we had received. By and large, most Santa letter companies are kind of flighty.
Package from Santa has always been very steady and professional.
