Buy.com price inaccurate

I am looking for a high speed SD card. You pointed to a Mach Speed 512 card at Buy.com:
"Mach Speed 512MB Secure Digital Card for only $58 - $40 rebate = $18 w/ free shipping."
The link gives Buy.com price of $67.99, but does have the rebate and free shipping.
How do I get the lower price you mentioned???

Larry, buy.com changes price quite often. We only verify the price at the time of the posting. It seems to me that buy.com raised the price on the item.

I was just surprised since you had just posted it yesterday. Perhaps Buy.com realized that, and pushed the price up as a result.

No problem. I'm new to this, so just needed to check it out.

Thanks for your help.
