I ordered 2 artbooks (A4 size? roughly?) from book depository in early January. They were posted on 9 January and I still have not received them

I stay in KL, so normally airmail from overseas takes about 10 working days to reach me. I'm hoping that it's just been delayed due to CNY deliveries and all the public holidays we had in January.

As they are quite oversized they probably cannot fit into my letterbox... in such a case, would the postman ring the doorbell or leave a note if no one is at home to receive it?

Thanks for the reply. So far, no package, no note.

I contacted Pos Malaysia about it and they want a tracking number. So I asked TBD if they have a reference number of any sort, but they just told me to try contacting my "local sorting office."

I'm quite at a loss as to what to do next.

Sounds like someone at Customs wanted a free read

well, this is a surprise...
I got a yellow notice from Pos Malaysia yesterday telling me to pick up a delivery from the Pos Office Besar. Turns out it was my TBD order... two and a half months late. I went to collect it this morning and the counter guy handed me a white gunny sack  Inside were my two books, still packed securely in a brown cardboard box. The shrinkwrap on both books was intact, so it doesn't seem like anyone tried to sneak a free read.

According to the Customs stamp, it was released by Customs on ?3 January, so apparently it's been... just... sitting in the Dayabumi basement for the last two months. Wow. Good job, Pos Malaysia.

I've emailed TBD asking them how to pay for them since they did indeed arrive. I wonder if they get this a lot?
