When ordering you have to choose an option:
Deliver within 4-10 days or 7-21 days.
7-21 one requires about 18$ for ship, and 4-10 one requires about 38$. Almost 2 times more expensive.
1 year ago we could choose "7-21 days"... but now we cannot. So you have to pay extra charges even if you're not in a hurry.
6 days ago I ordered a hoodie with the option "deliver within 4-10 days". Landmark tracking said "current statue: shipment data uploaded". And 6 days later today, still "shipment data uploaded"! Said Deliver within 10 days, and no progress in 6 days? What are you thinking?
I can tolerate the time my product arrives delays as I live in Japan, you have to send a thing over the sea. But if it delays because the process that can be done in u.s. progressed late, it's no excused.
Even I lived in u.s. my product would arrive late. There are only 4 days left and current statue made no progress.
