I, like you, am totally in the dark as to what the DS clerk is saying about the "perks" of the purple card. If a few lines of written verbiage about upcoming new events or maybe a special mailing once in a blue moon are what she's touting, then I can say, yes, I've seen that.
As far as points adding up to anything, the purple card had nothing. The only perk I got was through the club membership's 10% discount on WDW or DS purchase and then I'd use the purple card to charge.
And the new Visa is NOT a replacement to the DC membership card. That's been hashed and re-hashed on other threads. This Visa is a separate line of credit that (carelessly) has been represented to many people as just a replacement. Thus, some folks credit has been all screwed up because they didn't realize that by adding a new card and, say , cancelling another, will impact their credit ratings. Also, transferring balances has fees associated.
I agree that we all have responsibility to knowing what we're getting into, but there was a bit of Disney hype about the Visa being a replacement, which it is not.
