Amazon.com said the trees, wreaths and garlands will go on sale in November. Some will qualify for Prime free shipping, and Amazon will offer pre-orders so shoppers can choose a delivery date.

The company sold trees shorter than 3 feet last year, and some other merchants sold bigger ones using its platform as a marketplace. But this is the first year Amazon is offering the larger trees itself.
