While we have to make profit out of our biz, just like all other honest merchants do, we try our best to provide the best service and to keep the price as low as possible. Then the Discount Program was born.
There're 4 kinds of discount for the moment.

(1) Registration Discount
(2) Order Level Discount
(3) VIP Customer Discount
(4) Paying Method Discount

(1), Registration Discount

All new customers get a discount for their first order. Currently it's 5%.

(2), Order Level Discount

The Order Level means the final total amount.

Order Value < 25$	-- Discount 0
25$ <= Order Value < 50$	-- Discount 1%
50$ <= Order Value < 100$	-- Discount 2%
100$ <= Order Value < 200$	-- Discount 3%
Order Value >= 200$	-- Discount 5%

(3), VIP Customer Discount

After placing the first order, the Registration Discount will no longer exist. But the VIP Customer Discount program will be applied. The discount rate depends on the max final total amount of your past orders.
For example, if the final total amount of your 1st order is 550USD, the VIP Customer Discount rate will be set to 5%, according to the above table. The upgraded/updated VIP discount will be applied to the FUTURE ORDERS and not to the current order being made.
Please note that the rate will be UPGRADED automatically when you place larger orders later and WILL NOT BE DOWNGRADED.

(4), Paying Method Discount

We accept several paying methods for the moment, like PayPal and Bank Transfer. While PayPal is the most popular gateway, we do encourage our customers to use Bank Transfer as it will save the transaction fee so that we can provide better price. For large orders, the discount could be very impressive. Please note that the discount for bank transfer are only available for orders over 500USD.
Currently:

-- discount 0%

The discount types are cascaded. For example, if you get 10% as Registration Discount, 10% as Order Level Discount, 6% as Paying Method Discount, what you will get would be (1-10%)*(1-10%)*(1-6%) = 76.14%(23.86% Off) and not 1-10%-10%-6%=74%.
