Postal Costs when selling CD's

[mapleleaf-collectibles]

I decided I would sell my CD collection before they are 100% worthless. I know when I sell a cd to a Canadian buyer I can send it cheap by letter mail for about $3 or $4.  In the past I was told by a Canada Post clerk that a CD in its case can not be sent letter mail to the USA, and it can only be paper in the envelope.  That makes the cost of shipping to the USA around $9.00. Is there some way around this? Can you send a CD in its case to the USA as a letter?  Thanks for the help!

according to Canada Post no ...

Letter mail rates to the USA and International destinations apply to printed matter only.

Letter mail as defined by Canada Post and what constitutes as acceptable and unacceptable can be found here:
