HD upgrade for macbook...too cheap to be true ?

[Jenheta]

Zipzoomfly has some OEM hard drives at strangely low prices.
I've never had a bad experience with them but what's your take ?

Costco is selling 250MB WD Passport drives for $140 so I don't see why a bare WD drive can't be $104.

Usually I see competitive prices between Zipzoomfly and Newegg but this time the margin is sort of off. Somehow it feels that there must be a hidden catch somewhere

update : I compared the wrong model when I wrote the post...anyway, WD is still way cheaper. I might go with Seagate then . Newegg prices :
