Transcend TS8GCF80 8GB 80x Type I Compact Flash Card

They delivered my old version of CF(Orange One).
I called Customer service, do you know what they said?
"We are temporarily out of stock, so we sent you upgrade one(better one)"
Do they think we are ***.
As you know Orange one says 135X & blue one one says 80X.
But blue one(brand new one) is faster & more expensive.
I compared two CF with my RebelXT, there was slight difference in writing speed in Full Burst with Raw.
I hate this oneline transaction.

Ultra 80X CompactFlash memory cards are the best choice 4 use in high-resolution digital cameras & other high-performance devices.
