It was probably me -- that's my home turf.
First I'll get the hard part out of the way ... thrifting here in C-U is rough. Not much good, especially this time of year. With that aside, there are three thrifts in town ... all of which are on the Champaign side:
1) Habitat for Humanity Re-Store (40 E. University Ave.) - Probably the best for decorative arts, and definitely tops for furniture. No clothes at all.
2) Goodwill (1102 N. Prospect Ave.) - This is a sad, sad little store, but there are lots of clothes so you may luck out with that.
3) Salvation Army (2212 N. Market St.) - Again lots of clothes. Maybe not quite as sad as the Goodwill.
Depending on what other stuff you're looking for, you could check out Dandelion (9 E Taylor St) for a good selection of hip vintage clothes but not at thrift shop prices (although not terrible). You might also like the Furniture Lounge (9 E University Ave) if you are into mid-20th century design. They've got clothes, furniture, dec. arts, etc. A great store, but they know what they have (for the most part) and charge you for it.
About a 15 minute drive north is also A Second Choice (100 E Sangamon Ave, Rantoul), which is a thrifty-style consignment shop. It is a for-profit thrift and consignment shop, so it isn't listed in the directory here at The Thrift Shopper.
What kind of stuff are you looking for? Ask away -- I'm all ears!
