First, confirm the amount you need to check
When purchasing a Real Madrid jersey, the price on the product page is not the same as the final amount due on the payment page. When checking, you should record the product itself, service fees, payment fees, packaging fees, exchange rate, and international shipping separately, and use the amount shown on the checkout page as the standard.
The product page corresponding to this article is a black retro-style Real Madrid jersey with white dragon pattern, and offers different number, color, and size options. According to the page information, the reference price is $12.22, and the page also shows a final product price of $13.48. The information does not provide fixed values for service fees, payment fees, packaging fees, or international shipping, so you cannot calculate the total order amount based solely on these two prices.

Step 1: Record the product fields separately
After opening the product page, do not rush to calculate the total price. First record the options that will affect the product amount and subsequent shipping:
- Product name or style: black, white dragon pattern retro Real Madrid jersey
- Number or no-number option: the page lists multiple number options, including some player numbers and a no-number version
- Color and whether socks or pads are included: different colors and combinations may correspond to different product options
- Size: children's sizes are #16 to #28, adult sizes are XS to 3XL
- Quantity: confirm whether it is a single item or multiple items
- Page price: record the reference price and the currently displayed product price, and save a screenshot of the page
The page also states that size measurements have an error of 1 to 3 centimeters. This information is for size selection and should not be used as a basis for fees or discounts.
Step 2: Distinguish reference price, product price, and total amount due
The product page information shows both a $12.22 reference price and a $13.48 final product price. Both are product price information on the page, but they do not mean that service fees, payment fees, packaging fees, or international shipping are already included.
You can create a record as follows:
| Cost field | Currently confirmable content | Where to check before payment |
|---|---|---|
| Product reference price | Page shows $12.22 | Product page and saved screenshot |
| Product price | Page shows $13.48 | Reconfirm after selecting number, color, size, and quantity |
| Service fee | Information does not provide a fixed value | Shopping agent checkout page |
| Payment fee | Information does not provide a fixed value | Payment method confirmation page |
| Packaging fee | Information does not provide a fixed value | Order or warehouse settlement details |
| International shipping | Information does not provide a fixed value | Agent platform shipping calculator or final shipping checkout page |
| Exchange rate impact | Need to confirm based on conversion result shown at payment | Agent platform and actual payment channel |
| Final amount due | Cannot be confirmed from current information | Final payment confirmation page |
Therefore, you cannot write $13.48 directly as the total order amount, nor can you claim a fixed gain or loss based on the difference between $12.22 and $13.48. The information does not explain the complete pricing conditions for these two numbers, nor does it provide real-time rates, discount conditions, or package parameters.
Step 3: Review item by item according to the payment process
1. First lock in the specific product options
Confirm the number, color, whether socks or pads are included, size, and quantity. After options change, the product price may need to be reloaded. If the page does not clearly show whether a certain combination is available for purchase, pause and do not estimate based on the lowest price.
2. Record the product amount displayed by the agent platform
The product page provides an entry for purchasing through Kakobuy, but the page information does not provide complete checkout details. After entering the agent platform, check whether the imported product link, style, quantity, and product amount match the original page.
3. View service fees and payment fees separately
If the checkout page displays service fees, payment processing fees, or other order fees together, expand the details and record them separately. The information does not provide fixed values for these fees, so do not apply rates from other orders, other agents, or past settlements.
4. Check international shipping after package information is confirmed
International shipping usually requires destination, package weight, dimensions, shipping line, and service options. The current information does not have these parameters, nor does it provide real-time shipping rates, so before payment, use the agent platform's official shipping calculator or the final shipping checkout page as the standard.
5. Check exchange rate and actual deduction currency
If the agent platform displays in US dollars, but the payment channel deducts in another currency, record the platform conversion amount, the exchange rate used by the payment channel, and any possible payment fees. Do not replace the actual conversion result on the payment page with a market exchange rate found through search.
Conditions to pause before payment
In the following situations, it is recommended to pause payment and save a screenshot:
- The style, number, color, or size on the checkout page is inconsistent with the product page
- The product amount only has a reference price, without a clear price corresponding to the current options
- Service fees, payment fees, or packaging fees are not itemized
- International shipping has not been calculated based on destination and package parameters
- The currency or exchange rate displayed by the platform is inconsistent with the actual payment channel
- The page cannot confirm stock, purchase availability, or whether the link is still valid
The public information for this product has no buyer feedback and only one independent public source. The page recommends choosing based on the size chart and states that there is not enough buyer try-on or fabric feedback. Therefore, after completing the cost check, you should reconfirm whether the product page and agent platform still accept orders for that option; do not treat the page's existence as confirmation of stock.
Finally, recalculate with a simple formula
Before payment, you can copy the checkout page numbers in the following order:
Product amount + Service fee + Payment fee + Packaging fee + International shipping ± Exchange rate conversion difference = Actual amount due
If a certain item is not shown, mark that item as "unconfirmed" instead of filling in zero. Only when all relevant fields can be found in the agent platform checkout page or official calculator is it appropriate to continue with payment. The current information can confirm the $12.22 reference price and $13.48 product price on the product page, but cannot confirm the final total including all fees.
