Query: Wrong one

I'm so angry... I have a Sony DCR-HC90 camera, and on amazon, it suggested I buy this memory stick. So I bought it, opened it, and found it that it's the wrong one. My camera only takes duo size memory stick. Now, I will admit my ignorance between standard size and duo, but I'm really upset that it would suggest I buy this memory.You'd think it would know what was compatible with the camera and not. grrrr
