Yes, we know it's something our parents would say. But it's true: "They just don't make things like they used to." Go to a regular retail store and you'll pay a hefty sum for a picture frame made of, we shudder at the thought, plastic. Not so at Arc's thrift store (proceeds benefit the nonprofit Arc Hennepin-Carver), where an eight-by-ten-inch oak frame goes for less than two bucks. If you're looking forward to serving up this summer's iced tea in a pitcher that's not made from a mold, you'll find a wide selection of ceramic and glass beauties just like Grandma's for under $5. A set of Robin's-egg-blue wine glasses was recently going for $6. We even spied a vintage croquet set for $10. One of several Arc locations, the Richfield store doesn't sell large furniture items--so every square inch of space is devoted to displaying those little knickknacky things that make a house a home. Lace curtains, colorful afghans, kooky lamps shaped like covered wagons, they're all here for the taking, for little more than the spare change in your pocket.
