I thought it would be a good idea to have a thread where we pointed out some of the best places on the internet where there's and opportunity to get amazing deals on autographs.  It can be in the realm of sports, actors, music . . .  

Here are some that come to mind:

Newbury Comics (website and ebay) - Autographed CDs.  Most are the cost of the CD, though some of the more limited items may have higher prices.

Schwartz Sports Memorabilia (ebay) - Sports and some celebrity autographs.  Have $9.99 auctions for great sports autographed items from their own public and private signing.  Chicago-based, so heavier in Bears, Cubs and Bulls items, but also has low starting bids for Pete Rose, Reggie Jackson, etc.

Radtke Sports (ebay) - Sports autographs.  Similar to Schwartz in that they have low, low starting bids on items from their own signings.  

Waukesha Sports Cards (ebay) - Sports autographs.  Most items have flat (or best offer) prices, but the the low starting bid auctions are quite frequent.  Specialize in local stars (Packers/Brewers).  Great place for Lombardi era Packers items.

Autograph World (website, UACC auctions, and ebay) - Celebrity autographs.  I think just about everyone on this website knows about them.

JG Autographs (ebay) - Celebrity autographs.  Low starting bids to many of their ebay auctions.

NewGraphs (ebay) - In-person celebrity autographs.  Ebay in-person collector sells items at fairly standard prices throughout the year, but the past few Decembers has had huge fire sales at the end of the year.  You can score amazing deals on celebrity items, some of which may even have exact photographic proof.
