what is the recommended method to send an item to uk? there are so many options, pos dafter, e-parcel etc...
i heard some methods would take 2 months to reach uk. i want a method where my item can reach uk within 1 month, of course i dont want an option that is too expensive

Depends on your item. Is it a large item, heavy? Or just a piece of document?

Since time is not much of an issue here, you can go for registered airmail (pos daftar, international blue color sticker and need to stick blue color airmail sticker). For documents, usually cost around RM10 or so when I send to Canada. Reaches within 2-3 weeks.

If huge item, I use International Parcel Post, run by Poslaju. Cost around RM100 or so for a box about roughly 20kg, send to NZ, reaches around 3-4 weeks. They say longest 3 months though.
