Good site. Brand name products at reasonable prices. One gripe: I bought 2 hard drives that involved rebates directly with ZZF. I didn't receive the rebates anywhere close to the stated dates. Finally, I had to file a complaint with the FTC. I then got the rebates. My advice - stay away from ZipZoomFly if the rebate is important to you.
I too ordered 2 DVD's from this site via PayPal. I never received them. I opened a dispute with PayPal and got my money back. I see a common thread here.
