Why is freestuff from Renderosity NOT free?

Sometimes rendo offers items from the store for a limited time for free, like "Luck O' The Green" today.

But different to all other shops (DAZ, RDNA) who offer similar products for free, we have to pay a minimum of 3.50$ to get them. That is not free.

If Rendo would have his headquarter in Europe we could sue them for misleading advertising.

I hope they will change it immediatly. Thanks for the vendors to give their items free. But as long I was compeled to buy other things to get them, Rendo do their customers no favour. To say, they have a "Free Stuff" section did noit count for me, 'because most of the items from there can anyone also download at ShareCG, DeviantArt or other related sites. Rendo did not host them on their own servers.
