Shipping times are long or expensive. I&#039;ve been spoiled by Amazon free shipping.

The ordering process was simple and straightforward, especially since I used PayPal as the payment option. Items received in excellent condition, safely packaged. The product takes around 1 week to reach Sri Lanka via Hong Kong air mail, and you have to visit the CME to collect and pay 10% tariff. I will be purchasing more items in the future.
