I agree with Firebirdz...the expenditure is well worth it, and although that chunk of change is a large amount to spend, it usually makes up for itself with just a few weeks. If you have copies of your purchase numbers that you should have received in email, I would write a letter to sales@daz.com asking them that if you joined the Platinum club, would that be willing to credit the price differences from regular purchase to pc club purchase price to your account as a credit since the purchases were made within such a short time frame. I don't know that they would do so, but I would certainly ask. But, you'd have to step up to the bat and join if they would make such a concession for you. Never hurts to ask, all they can say is yes or no .
