Bella, I don't know about sending to France, but I've had no problems receiving items FROM France...
If you send the CD as a parcel, it would be $11.00 airmail. (Registered airmail would be $23.90.)
If you send it as a letter (I think you can if you put it in one of those CD boxes), it would be $6.30 airmail. (Registered airmail - $12.00.)
(Anything larger than 260mm x 360mm, thicker than 20mm or heavier than 500g is considered a parcel.)
