Rant- Ebay seller and the cost of shipping 1 cd.

Hi y'all. I apologize that this more of a rant than anything else, there is a cd that I want to buy, the cd is $8.51 'buy it now' option, which is ok, now the sellers shipping charges.
To quote:

$6.99 Kinda Slow (12-21 Days*)
$7.99 Best Value (6-9 Days*)
Much faster delivery time for a little more. Insurance is optional at checkout.
$16.99 Really Fast (3-5 Days*) additional item $9.99.
Insurance is included with this service.

I have purchased many cd's from all over the US and I waited probably a maximum of 7 days to receive the Item/s, even when i order from the EU.
Does anyone think these postage charges are reasonable to have 1 cd shipped in the US, or have I just been spoilt or lucky?
I usually pay about $2.65 for a single cd shipping in the US. When I send cd's to friends in the shipping is $1.65 excluding the puffy yellow bag. I think it is about $5 to send to EU (if my memory serves me)
I can and do appreciate that a small profit should be made when a seller sends a cd.
Any body else got any views/queries about shipping charges that they have Incured?
