I sell my small bags for $30 and larger totes for $50. BUT! I make them out of vintage barkcloth. A large tote may cost me $25.00 in fabric (one yard)> And I use fusible fleece and generally do not quilt it. THere is enough texture and interest in the fabric itself and I don't want to compete.
You might check out Etsy and Artfire and see what the prices look like for different styles. I think on both sites, some are frightfully overpriced, and some underpriced. It depends on your area.
Good luck!
