We'd be hard-pressed to think of a better method of whiling away an afternoon than sifting through vintage furniture and goods. And that goes double when there's a deal on the table. Which is precisely the case with Third Thursdays at Zinnias, when the multi-level Melrose Curve shop knocks 20 percent off of nearly everything in stock, save for the fancier furniture in its front room. No matter, though. The rest of the antique shop is stacked with goods, ranging from Pyrex dishware and midcentury couches to vintage magazines and framed artwork that might just be the finishing touch you've been looking for.
