Okay. Civil people. Here's listing down some answers I've summarised from pages of posts.......
1) Miscommunication between hwood and myself, he charged shipping that's slightly lower for those people that he invoiced, resulting in the differences between both our invoices. He will be rectifying that soon, by asking people to top up the difference. You can reduce your order if you desire, he should be able to handle it for you.
2) I am shipping via Intl Air Packets (airmail, contary to what you read, they allow boxes) + registered mail (aka tracking & signature required on receipt, which costs +2.5/package), and they do not allow packages larger than 2kg, hence many of those who ordered larger quantities have been billed WITHOUT shipping, because the price estimates go haywire after 2kg, and I'll need to go get the exact prices for the best way to send them their items.
3) Shipping costs include costs of materials as well, bubble wrap, ziplock bags, boxes (I'm getting the thick walled ones so they don't dent/crush during shipping, and NO I'M NOT USING BUBBLE MAILERS), tape, shipping labels etc etc, and any additional costs to travel and source for the stuffs and ship them (it is insignificant, but since people wanted to be clear, I had to mention. Or people will think that petrol comes free from wells in Singapore). The small difference will also buffer in case the packaging jacks up the cost of shipping, they weigh quite a bit together as well.
4) GB fee includes a $2 tip for us per order for sorting and packaging services, and the other 1.5 is for consolidated shipping from Gateron to Singapore for the switches and the 7% customs charges I'll get for importing the switches.
5) Please also bear in mind the 4% PayPal fee and currency conversion, banks don't use the Google rates.
6) The price you pay on your invoice includes everything above, I used to do GBs and ship stuff frequently, so I know most of the things that I need to include in my bills from the start, so they might look abit more than expected. BUT you do not have to worry about me slapping on additional charges when it's time to ship the packages, which you might have seen on other GBs.
EDIT: Before you think that the price is outrageous for such a cheap item, go quantify it by looking at a baggie of your own switches lying around. The percentage of the shipping might be really large in the invoice, but when you divide it out the cost becomes more realistic.
Any other burning questions?
