Some online retailers have already discounted the new suite by as much as $40.
Though Microsoft has no plans to promote the new office suite with special deals, retail partners are free to run their own sales, a Microsoft spokeswoman said by e-mail.
On Monday afternoon, Amazon.com listed the lowest-priced edition, Office 2010 Home and Student, for $129.99, $20 less than the list $149.99. Another online outlet, Newegg.com, listed the three-license home edition for the same $129.99.
Amazon's prices for Office 2010 (see review) Home and Business and Office 2010 Professional were $40 less than list price, or $239.99 and $459.99, respectively. Newegg matched those prices as well.
Set to debut Tuesday are lower-priced "key cards," a new way Microsoft will sell Office. The cards, which contain a single-license product key, can be used to upgrade older versions of Office or activate a trial edition or copy that's been downloaded from Microsoft.
A key card can also upgrade a copy of Office Starter, the new stripped-down version that OEMs preinstall on new PCs, to a full edition.
In January, Microsoft announced that it was dumping upgrade pricing, a long-standing hallmark of Office's retail price structure, and said the key cards would replace the discounted upgrades.
A one-license key card for Office 2010 Home and Student, for example, will run $119, with Home and Business cards priced at $199. Office 2010 Professional's cards will cost $349.
From the discounted prices now available at Amazon and Newegg, it appears Microsoft's retail partners are not allowed to drop prices of the disc-based editions below those of the corresponding editions' key cards.
Microsoft officially launched Office 2010 at a New York event on May 12. Business customers with volume license agreements have been able to obtain the new suite since then.
