I've ordered some parts from Concept Z (Moulding kit, T hook, Hinge covers) which weigh 5kg when packed. How much should I be paying for shipping (surface mail)? $130 seems a bit steep
Coz becomes more cost effective as you order more gear and combine postage... although a lot of items are still cheaper with postage from US/Canada than they are from places like UAS etc. I'd say $130 sounds about right, i ordered in the moulding kit last time and it does take up a bit of room length wise which is probably why postage is a little expensive.
You can get an idea by looking up USPS website and try to calculate the cost yourself. Looks like the size hurts you in this case. Coz's prices are very close
