Query: How can you mess up something so simple???

They sen't me a SD card for a Digital Camera, instead of the one I needed for my cell phone. You'd think a place that sells this stuff on a regular basis would have noticed the big diffrence between the two items. The one is 3-4X bigger than the cell phone SD card. Waste of $$$, and a headache I'll never deal with again. FAIL!
