I used to get sales coming in from them, but haven't since March even though there's some traffic to those pages and a number of clicks to them. So I looked at their recent history at SAS:

Last Commissionable Transaction through Affiliate: 04/12/2007 01:26.15 PM
And then, someone posted in August that a purchase didn't track:

First purchase with them did not track. I've notified them.
The last SAS compliance test shows as June, but are they still alive and kicking as an active merchant?
