I just heard that Fictionwise has ended their Buywise Club, but that's not completely accurate. It appears that Fictionwise is no longer selling new memberships or renewals, but existing members can still take advantage of current sales. I'm waiting to hear from Fictionwise about what is going to happen to existing memberships.
There was no actual announcement that the club would end. The first anyone knew it had happened was that Fictionwise added this to their website:
The Fictionwise Buywise Club progam has been discontinued. We thank you for you patronage and apologize for any inconvenience this may have caused. Thank you.
