I sent some packages to Turkey several times in the past (with registered posts).
None of them got lost and arrived in 4- 5 days.
What are you trying to do here? eh?
Trying to look for a reason to criticize Turkey? eh?

According to my friends who have lived in Turkey for over 10 years as expatriates, it took very long time to receive mail or parcels in the past. But now it is very much improved. I have sent small packages by speedpost from Hong Kong and it took only 2-3 working days to get to Istanbul. Yet I have not tried sending anything by surface mail or normal airmail. I would guess it should take at least one week by airmail. For remote areas or villages it seems normal to take longer time though.

We send books to Istanbul and it took two months. Than we send something to Antalya and it was there within a week.

Yes it just depends sometimes it can take about 2 weeks other times in my case it has taken about 6 or 7 days.All the mail i have sent to Ankara has been delivered! Have faith they are doing their best,fingers crossed it will get there eventually.

Time really depends on each and single individual who has anything to do with your mail. If they take too many tea breaks it may take an extra week

Hello friends, I´d like to send my friend a birthday surprise with a parcel to Turkey. I need translations help from E to TR lütfen

1) I hope I am not late, and this mail reaches you just in time for your birthday.

2) Many happy returns

3) when signing off, how do i write "Love from Singapore, (signs name)" ?

4) when saying a great surprise for (name), am i right to write "(name) için büyük bir sürpriz"?

Yardımlarınız için çok teşekkür ederim!

1) Umarım geç kalmadım, bu mektup tam yaş gününde eline ulaşır.

2) Nice mutlu yıllara

3) Singapur´dan sevgilerle, (name) xxx

4) Yes, you are right : "(name) xxx için büyük bir sürpriz" .. but sometimes saying "küçük"(little/small) instead of "büyük" may make better sense .. 

my post didnt arrive to istanbul for 3 months. theres only 50% chance that the mail will get trough. normal letters and briefs are ok but packages are risky

Çok teşekkür ederim! Thank you for your help

@burakk: haha yea i read about it in the earlier posts, guess it´s about taking the risk

When we were in Turkey, we sent postcards from Göreme to Estonia and Finland. We were long home before the cards came: a bit damaged but still got here, one of them more than 2  and the other more than 3 weeks later. According to the stamps it had taken a week for them even to start moving from Göreme

Now i sent a small package to Göreme. It reached Istanbul in 9 days and hasn´t moved since... maybe it can be a Christmas present instead of birthday present

Update: the package was delivered. It took 2 weeks and 1 day - so, pretty good, i think
