We have added support for two more columns in the products spreadsheet called 'condition' and 'brand'. They are both for google products (froggle) use only.
'Condition' of the item you are selling should be set to 'new', 'used' or 'refurbished' (new by default if none is entered) and 'Brand' is so you can include a product brand name so you can be included at the bottom of the search results if google shopping customers decide to click on that brand.
