In the options of the plugin, you can find the option "Price Displayed" which you can use to select what price will be added to the feed.
The prices are based on the current user accesses. If it's the cron task that you're using, the user will not be logged, so it will display the prices with the unregistered user group.
However, if you download the xml from the options of the plugin, it's your user group which will be used.
That would mean that your user group (super administrator I suppose), is also in the wholesale group or that you added your user group to the prices for the wholesale group.
