There's no real free returns.
That said, you have the option of getting credits for your next purchase, which will be available aprox 3 weeks after you send the item back to Rue Lala, giving you a very short time to be able to benefit from your one-month free shipping. They won't give you extra free shipping time.
And the second option is to get a refund, with a charge of $9 for the shipping cost. And lets say you returned more than one item in a month, in separated packages. In this case, you will pay the shipping fee for each.

Defective item.
Lets say you bought a defective item. They will apologize and accept the return without charging you the returning shipping fee, which is very appropriate. But lets say you want to keep the item and fix the problem. In this case, they won't take any responsibility and won't give you any bonus nor a parcial refund. Photos and videos that expose the problem very clearly won't be of any help. They did give me an extra month of free shipping, which was nice but at the end provided them more money from my new purchases.

Sale of real wildlife fur.
I don't expect the business to do charity to wild life, but real fur is something that disgusts many buyers nowadays. It doesn't sell as much as other items, but there is a public for that cruel market. I don't agree with the use of real fur of wild life for fashion unless the fur comes from a certified hunter from Alaska or any place where people hunt for survival - which will never happen. The cruel methods of fur removal is widely acknowledged and exposed on internet (not recommended for highly sensitive persons). Everybody knows that these poor animals are caught and breeded exclusively for their fur; and that electrocution is the major method for killing them, which sometimes doesn't guarantee their death and leads to their fur removal while still alive.
Rue Lala sells real fur from rabbits; foxes; and chinchillas. (As far as I've seen).
