Apparently, the offer only went out to a select few.  They seemed to be people who were long-term members who opted out of the PC.  So who knows, maybe you'll get it once you cancel.  (You have to cancel it according to their directions, or you will be auto-renewed.  Even if you remove your credit card or even if the credit card is expired.  Which I think is pretty obnoxious, but that's another issue.  Also, if you disable the auto-renewal before your membership is expired, you lose the rest of your subscription.)

The new value category has items for $9.99 or less, available to everyone.  For PC members, the items are $1.99 for the first two weeks, then they go up to $2.99.  DAZ says these will not replace the traditional $1.99 items; in fact, they promise more $1.99 items each month than there were before.

It does seem like it's an incentive to buy now.  Rosity does the same with their Prime items.  Makes sense.  There's little incentive to buy the regular $1.99 items before you need them, since they're always there and the price only goes down, never up.
