Shipping is always a bit of an headache.
When I bought my complete @ OG I spent almost 600€ so the shipping was not included and I didn't pay anything else but that. The problem comes when you only need a couple of parts that don't get to high on the price tag, that sucks alot since most of us have no alternative than buying online..
The last time I tried to simulate buying something @ FlatlandFuel my nuts almost fall off when I looked at the final price for the parts I had chosen, a "theft" really, overseas shipping is out of the question.
