Hey guys,

So a current client of mine has an e-commerce shop with a few hundred products. They purposely choose to keep the prices off of their website, which is causing errors in Google Webmaster Tools.

Basically the error shows:

Error: Structured Data > Product (markup: schema.org)

Error type: missing price

208 items with error

Is this a huge deal? Or are we allowed to have non-numerical prices for schema ie. "call for quote"
