Well, if you are looking for small stores for your every day items like groceries, clothes or a new tooth brush, than look in new Cornwall. There are many shopping malls like this on the image. You can also go into one of the larger department or grocery stores like Super-C or Loblaws.
What to buy: Everything you need. Banks with ATM, Post cards, clothes, soap, shampoo, garden, food, drinks, electronics, CDs, flowers and so on.
What to pay: Set prices
Here is an antique store looking place.
It is more like a thrift store, selling used merchandise. I've spotted this genuine native, Indian tent from a mile away. It's not something you see every day. It is made of wood and real leather and animal skins. There are many native people live and work around Cornwall. This tent on the picture is designed to be a toy for their children but it's still interesting because looks just like the big ones.
Ps: The image is not D. Johnson's. it's another one. I recommend visiting D. Johnson's though for real antiques.
What to buy: Used books, paintings, furniture, glassware, jewllery, oil lamps, China, postcards, ironware, etc.
What to pay: Haggle on the price if you can.
