Not sure if this is a deal (Mods: feel free to move to the Forums if you think it isn't) The community has spoken and decided that, yes, this should be considered a deal. It's definitely free and doesn't cost anything in the form of travel or entry fees. Per a newsletter article I received today, The Louvre is now making their entire art collection available online in a series of browseable albums. This means you can enjoy one of the largest collections of historical and modern fine art from the comfort of your own home.
Note: this is different to the free virtual tours they had last year.
