I recently fell victim to their ripoff rates. At 4 dollars per 0.5kg, it seems relatively fair on top of the promotional voucher given previously. Had i gotten my products delivered from Amazon, threadless and think geek delivered seperately, delivery would have cost me about $85. Which was why i used hopshopgo thinking i could save about 20-30 dollars. How wrong i was.
The total for all the postage cost me over $157, and this doesnt include Fuel surcharge and what not. Even wiht the promotional voucher and the paypal 10% discount, it costs me an extra 30-40bucks to have my items arrive more slowly. They get you by using "volumetric weight", where an item weighing 3kg might be charged at the rate of 7kg because of the box size.
BEWARE Ozbargainers!!!
Generally the reason why you use them is because the site where you buy from doesn't offer shipping. Adding a middleman who always makes a profit would naturally make things more expensive.
