electronicfly, do you have any experience dealing with United Kingdom Royal Mail?
I've bought hundreds of stuff from the US through USPS/Fedex/UPS and also hundreds of stuff from China & Taiwan through UPS/EMS.

But this is my first time dealing with UK Royal Mail.
The seller send the item using Royal Mail International Signed For™

He also gave a tracking number and it's trackable through Royal Mail website, but I'm not sure what's the next step once the item arrives Malaysian shores.
Thankfully, the seller wrap the item in a birthday wrapping paper, hoping that Malaysian Customs won't tax my item since it's less than RM400 anyway.

Wow, a new moderator here makes me look like I'm talking to a wall.

1. Arrive at home.
2. No, because the stuff I bought and shipped through CPAP & HPAP are mostly below 2 units.
3. No.

For huge quantities, I always opt for UPS, as they are the most reliable international shipping.
Fedex is not even close to what UPS can offer.
