Can introductory text be before grid products?

Using the MarketPress plugin, I would like to have an introductory welcome papragrah or two before the product grid. I can't figure out how to do this. I have it as a regular post in WP; is there some other place I need to put this in order for it to show up?

I am starting to 'get' this plugin and the GridMarket theme, I think there are just a few things left I haven't quite figured out.
