Frog Hollow is a gallery for the Vermont State Craft Center - there's a second location in Middlebury - and they showcase a very diverse array of high-quality items by local artists: some of the items have a pretty hefty price tag, though there's really a wide variety of options. They have an extensive stock of work by well-known artists like Sabra Field (famous for unusual prints of Vermont), as well as newer people on the scene. They always seem to encourage extensive browsing, and the staff are always happy to help you with a piece of jewelry or information about an artist.
As with any college town worth its salt, Burlington sustains several bookstores, and Crow Bookshop is probably the most unique. They specialize in second-hand and overstocked books, and they have a huge selection of books for an academic audience as well as very impressive sections on cooking and gardening: we found it very easy indeed to while away some time before dinner browsing their shelves. The books were well-organized, too - not something that is true in all second-hand stores - and from our experience the staff seemed very helpful and aware of what they have in stock.
The Church Street Marketplace, located in the heart of Burlington, is a fantastic place to shop, eat, sip coffee, people watch and much more. I was even lucky enough to catch a really funny street performance. It is approximately four blocks long and closed off from traffic (pedestrian only) which means you can wander around and not have to worry about getting crushed by an 18-wheeler.
What to buy: There is a little bit of everything here, from the big names like Borders and, well, that big, green coffee company to small, local shops. I particularly enjoyed Speeder and Earl's coffee.
What to pay: Depends where you shop and what you're buying.
The Church Street Marketplace is an award winning pedestrian mall with 130 shops, services, and restaurants. It's a great place to take a stroll. You will see unique products from local artisans and there is a Lake Champlain Chocolates store that sells local chocolates, chocolate happens to be my favorite candy and by my standards it's excellent.
What to buy: The local arts and crafts will not dissappoint you. There is everything from glass to wooden items for every appetite.
What to pay: The local artist's works vary, some are very expensive.
Filene's reminded my of the Macys stores. Good quality merchandise with sales throughout the store. It's located in the Burlington Town Center Mall. When you exit the from the east side of the mall you will end up at the Church Street Market Place.
What to buy: Warm clothes if you didin't bring them.
What to pay: Comparable to Macys.
