Educomp

They have stickers! I needed gems for my halloween costume and they had that plus more

Educomp is one my my favorite shops on the island, as it is filled with fantastic art supplies. Sure, they are more expensive than off-​island art stores, but when you have to paint, you have to paint. If you need a gorgeous gold pen, a ruler, some stickers, some hand made paper, some turpentine, some brushes, some watercolors or some erasers, go here. There’s a very efficient and (mostly) pleasant staff to help you if you have no idea what you are doing as you stare at this lovely array of products designed to throw you into a creative frenzy. Not sure what kind of brush to buy? Not sure if that kind of paint is water based? They will help you and not make you feel like a moron.
They also sell every imaginable kind of office supply, including all things related to Apple products. AND they have a sunny little office area for you to use if you need to make copies, send a fax or use a computer when yours is acting funky because it wants to be on vacation, too. It is HARD to work in August when you are on the island.
There’s a big parking lot in the back but you can also walk to it from anywhere in Vineyard Haven. It’s right in town.
When you are on MV, you are in an amazingly gorgeous place. Pick up some pastels or some paints and get out there with your kids and grandkids for some real fun. Just get your supplies at Educomp first.

typical computer/​school supplies/​copy center
not too expensive, and the people working there are genuinely helpful and polite
overall, good place… considering nothing on the island is chain, its the closest you’ll come to finding what youd expect at a staples/​office max/​etc

Yeah EduComp!
You can get your mac serviced here. You can get all kinds of art supplies. I love this place for their vast selection of pens — and you can test them out on the pads supplied.
I have a pen fetish so this place gives me a metaphorical semi.
