I've seen both higher and lower rates advertised other places than P411 for various ladies. Just as with the same person using different names, phone #s and emails they may simply have complicated things beyond their capability to keep track of what they're doing.
As for making your money back from provider P411 discounts that's kind of a myth as the % of providers that offer such discounts is so low that the use of discounts as a selling point smacks of used car salesmanship tactics.
