Also, if you happen to stop by Detroit...
Lately good shows are at the Corktown Tavern, The Painted Lady, the Maidstone/Gravestone in Ypsilanti, Small's, and PJ's Lager House. Something Cold sponsors regular coldwave/post-punk/industrial events.
Noir Leather in Royal Oak still carries some cool punk/fetish stuff. Thomas Video in Royal Oak is like a cult movie mecca and still carries lots of VHS. There's also Joe's Army/Navy on Woodward in Royal Oak for cheap combat boots, fatigues, etc.
If you are coming to Detroit, let me know what you thrift for and I'll pm some good thrift stores...
