In campaign setup, all the Goal does is narrow down the campaign types they recommend. Pick sales and make shopping campaigns. Create a high priority campaign with low bids, and a medium campaign with the real bids. You can use a location adjustment of -90% to reduce the bids on the High campaign. Load your target keywords into a shared negative list, and apply that list to the High campaign. The Medium campaign will only trigger on your chosen keywords, the high campaign will do a little bit of long tail discovery for you.
