Take advantage of the free events because they don’t last. Sure, there’s always the occasional promo on campus or National Doughnut Day over the summer, but the deals are less frequent and not as sweet as they are in September.
Here’s a list of some free or low-cost events you’ll want to check out. As an added bonus, I’m going to start the roundup with some early ones.

Downtown Crossing Block Parties (ongoing)
If you didn’t get a chance to check out the Downtown Crossing Block Party, make some time this week. The block parties offer free appetizers and nice selections on beer and wine. Not to mention music.
Hours: Sept. 19, 5-8 p.m.
Location: 32 Sumner St.
Admission: Free

Oyster Shucking Lessons (ongoing)
The North End Fish Market offers free oyster shucking lessons every Saturday. The lessons are free, but you have to pay for what you shuck and eat. There’s no need to make reservations for these. They can accommodate groups of up to five people in the market.
Hours: Saturdays, 1-3 p.m.
Location: 99 Salem St. in the North End
Admission: Free

Night of Stars
If you’re looking for some classy plans, watch the Boston Ballet’s performance free. The Night of Stars, which is open to the community, includes various pieces that the company will perform for its 50th season. The pieces range from classical ballet to contemporary dance. There’s also a “surprise world premiere piece.”
If it gets rained out, the performance will take place the following evening
Hours: Sept. 21, 7 p.m. (rain date, Sept. 22, 7 p.m.)
Location: Boston Common, at the corner of Beacon and Charles Streets
Admission: Free
Allston Village Street Fair
This beloved annual event draws BU students every year. The street fair has family fun activities and all that jazz you’d expect from a fair, but it also features promotional giveaways, local bands and artists and a taste of Allston’s international cuisine.
The street performances include Sidewalk Sam, Fictional Faces Facepainting, the Music Museum of New England and the Boston League of Women Wrestlers, among other groups.
Hours: Sept. 22, 12-6 p.m.
Location: Harvard Avenue, between Cambridge Street and Brighton Avenue in Allston
Admission: Free (food not included)
