I ordered the Starz Plus Pack on 7/24/2004. With the upcoming price increase, I asked for assurance that my $39 price for VOOM would remain in effect should I later cancel Starz or wish to subscribe to another Plus Pack. I was told in no uncertain terms by the CSR that there would be no price increase to my VOOM subscription price regardless of how many times I added or deleted Plus Packs. I asked to speak to a supervisor who verified this fact and noted this information in my account.
I called last night about another issue, but again asked about the above scenario. Both the CSR and her supervisor verified there would be no change to the VOOM subscription price through 2004 if merely changing Plus Packs. Of course, if you were to upgraded/downgrade VOOM<--->VA VA VOOM then I think the new pricing will apply.
Anyway, ask the CSR to place a note in your account when changing Plus Packs just to be sure you won't be Zinged by the new pricing structure. If you have any problems, PM me and I will provide you with the names and CSR numbers of the individuals I spoke to.
