Traveling Cart

The Traveling Cart, which is pulled by a pig wearing a fez and spectacles, appears every Sunday by at least 11am (still testing time it appears). It's located between the wizard's tower and the lake with a dock right against the top of the forest.

Now, what it sells, is the most interesting part. This is a typical for sale list for Sunday Summer 14 Year 1: (prices vary every time from what I can tell) Acorn Tulip Tulip Parsnip Seeds Quality Sprinkler Pizza Eggplant Large Egg Albacore Blueberry Tart Dining Chair Rare Seed

The woman driving the cart sells "Rare Seed" every time, but all the other items are seemingly random and both from every season and profession. One possible use of shopping here every weekend is to get items for bundles before they're available in game season wise.
