[pnpgm] shopping

[Alex Koponen]

The party will have a couple hours to buy food and goods.

Z'leyra will make sure that enough is bought to last the party till we 
get to Zarun. Examining her store of waybread she finds that her store 
of them is much smaller than she had anticipated so goes shopping to 
make sure that food for the party and grain for the horses is adequate. 
She does not want to buy a wagon or to bother with fires on the road at 
least till we get to Zarun.
