You are hurting my brain with all this thinking. :)
Ok here is my shot.

Buying
Name of Place: Space Town
Goods purchased: Refrigerators
Number purchased:90
Amount spent on goods:$49,500

Selling
Name of Place:Quaint Town $72,000

Buy low sell high....no time to dilly dally because....
We got to move these refrigerators.

Old Persons Joke!
