Our base price for chipped tongkat ali is 12 US dollar per 500 gram.
Whenever the purchased quantity is the double of a previously doubled
quantity, then the price is multiplied by 1.6 or, for quantities above 8 kg, by 1.8. Thus, the levels at
which discounts become effective are: 1 kg, 2 kg, 4 kg, 8 kg, 16 kg,
32 kg, and so on.
However, we do not ship round quantities for less than 64 kg, because
these quantities are shipped by postal service. Shipping costs are a
substantial portion of the overall costs; we therefore always stay
below the weight limits at which there is a stark increase of postal
charges. For example, we ship 1.95 kg instead of 2.1 kg. To arrive at
an overall package weight of less than 2 kg (to stay with the
example), the net amount of tongkat ali chips that we ship is 1.65
kg. For a quantity of 1.65 kg, the per-kilo price for 1 kg applies.
After computing quantities and prices of tongkat ali by the above
rules, we just add the shipping, packaging, and handling costs which
are different for airmail and surface mail.
The base price of chips per 500 grams is 12 USD. Up to the quantity of 8 kg, we calculate double the quantity at a price times 1.6. For quantities above 8 kg, double the quantity cost 1.8 times the price.
1 kg - 12 x 1.6 = 19.20 USD
**********
2 kg - 19.20 x 1.6 = 30.72 USD
30.72/2 = 15.36 per kg
**********
4 kg - 30.72 x 1.6 = 49.15 USD
49.15 / 4 = 12.28 per kg
**********
8 kg - 49.15 x 1.6 = 78.64 USD
78.64 / 8 = 9.83 per kg
**********
16 kg - 78.64 x 1.8 = 141.55 USD
141.55 / 16 = 8.84 per kg
**********
32 kg - 141.55 x 1.8 = 254.79 USD
254.79 / 32 = 7.96 per kg
**********
64 kg - 254.79 x 1.8 = 458.63 USD
458.63 / 64 = 7.17 per kg
**********
128 kg - 458.63 x 1.8 = 825.53 USD
579.78 / 128 = 6.45 per kg
**********
256 kg - 825.53 x 1.8 = 1,485.95 USD
1,485.95 / 256 = 5.80 per kg
**********
512 kg - 1,485.95 x 1.8 = 2,674.71 USD
2,674.71 / 512 = 5.22 per kg
**********
1024 kg - 2,674.71 x 1.8 = 4814.48 USD
4,814.48 / 1024 = 4.70 per kg
**********
2048 kg - 4814.48 x 1.8 = 8,666 USD
8,666 / 2048 = 4.23 per kg
**********
4096 kg (one 20-foot container) - 8,666 x 1.8 = 15,598.80 USD
15,598.80 / 4096 = 3.80 per kg
