anyone have any expeirence with them?

how long is the delivery time?

i order some books, and a bag from them on 24th August, and until now haven't reach. Called their customer service, they only can confirm that the shipped out the items already. They tell me to go and ask my local post office, which i already did but still no packages. Then they say might be custom delay, is it normal?

how do i go and check from customs?
