same here. in principle, one can mix and match serif and sans-serif fonts as deemed fitting, but this here seems to be a mistake. the designers wanted to use a font named Arvo, but failed to include it via @font-face. thus, the browser falls back to the default serif font.

That's... quite an unprofessional mistake to make.

If you have Arvo, the design looks sort-of-okay. I have more of a problem with the ad copy.

"Easily tag items to where they can be purchased" is non-standard English and doesn't do a great job of communicating what's going on.

I had to chew through it a couple of times to work out what it meant.
