Even if you don’t have the money or time to donate to charity, you can still do something for the greater good — and it’s as easy and painless as lacing up your shopping shoes. The Hub’s many trendy-but-charitable thrift stores make sure that those bent on doing good will also be looking good.

Boomerangs, one of the most fashionable of these shops, donates its profits to the AIDS Action Committee, which works to promote research and improve the lives of people with HIV and AIDS. On a recent Monday night, this Jamaica Plain store had poster-size framed photo and art prints ($35) on sale, plus the perfect accessories for cocktail parties: wine-bottle stoppers and cheese holders adorned with plastic grapes, bread, and a French-looking waiter ($2.99). Best of all, they were still in their original packaging, which means they probably came from another store’s overstock, as does a lot of Boomerangs’ merchandise. The clothes are equally stylish — and also in good shape. In fact, a few items still have their tags on. Recent finds include a brand-new J. Crew white button-down shirt ($9.99), a gorgeous HarvŽ Benard wool coat ($19.99), and a Talbots knee-length beige skirt ($8.99).

Planet Aid, whose profits go to programs in developing countries, has a similarly trendy look. With Christmas lights decorating the walls and indie music blaring, it feels almost like an Urban Outfitters’ spinoff. And the clothes fit that mold, too. On the racks: an Asian-style silk dress with black embroidered buttons ($20), leather jackets ($30–$55), and a retro polyester bowling shirt with a bowling ball and pins embroidered on the back ($26). You can also find accessories like bandanas ($1) and a leopard-print pocketbook ($7).

The Salvation Army Thrift Store, in Cambridge, has a less fashionable feel, but it’s a well-established charity that’s worth helping out. And you can find some good buys, like a pair of DKNY cargo pants ($7.99) and a 10-speed bike ($30). They also have quite a few retro-trendy clothes, like a green wool sleeveless dress that looks like it stepped out of an Army barrack ($5.99).

Allston’s Amvets also has a bit of a downtrodden feel, but it sells some killer merchandise. In this neighborhood of ever-moving students, you can usually find great housewares, like a five-piece white Formica bedroom set ($125), a microwave ($13), and scores of dishes and plates (50 cents and up).

Now you’ve got no excuse not to shop your way to a clearer conscience.
