The highest “First” item shipping fee will be taken as a base, then plus other items’ “Next” shipping fee as a total. For example, two pairs of Men’s RUNNING SHOES and one pair of SOCKS shipped to Mexico by Standard shipping, the product prices are $25.49 and $8.19 and the Standard shipping fees are as below,
| Product | First | Next | Quantity |
| RUNNING SHOES | $2.5 | $2.5 | 2 |
| SOCKS | $0.8 | $0 | 1 |
Then the costs of shipping two pairs of RUNNING SHOES and one pair of SOCKS to Mexico by Standard shipping are $64.17=$25.49+$2.5+$25.49+$2.5+$8.19+$0.00.
