Sent $100 express with RMA for TX-650 PSU, then found out replacement is on backorder

Sent my TX-650 PSU with an RMA, well, it looks like it might be gone a while longer. Corsair, who was not up front, took my $100 express deposit... for faster delivery, and in fact the TX-650 PSU is on back order.. which I only found out after doing a chat with Corsair and my RMA. They could just send me another model with same or higher voltage, I noticed Newegg now sells the TX-750 PSU for $85.00 which is less then I paid... ! and less then the $100 deposit I paid for express service (they refund after they receive your old unit, which they got today.). :[pouts:
