Marshall Code 25 - $199.99
Marshall Code 50 - $249.99
Marshall Code 100 - $399.99
No promo code necessary. Shipping is free, and no tax is charged if outside MD.
Sam Ash will match or beat these prices. You can call in at 1-800-472-6274 and get one shipped or go to a local store with printouts from the Chuck Levins website. Chuck Levins is an authorized Marshall reseller as shown at http://www.marshallusa.com/dealers.asp
so you should have no issues getting a price match (I went into my local Sam Ash yesterday in Atlanta and they matched the price with no trouble), though you will end up paying tax. However, there is less risk in buying from a store you can drive back to if something is wrong with the product.
The same should be true for Guitar Center, as they do price matching.
Alternatively, you can buy these on Amazon for the normal street price of $250, $300, or $450 respectively, and you should see on the product page that Amazon is offering 10% back on music/instrument purchases until December, but that still isn't as cheap as buying directly from Chuck Levin's or getting a local store to price match.
