It's automated dropshipping using API,
customer places the order on the alibitress, payment gets verified on blockchain, and order is automatically sent to the seller on AliExpress using their dropshipping API.
A credit card is attached with the AliExpress account to fulfill the orders.
All of the customer data is encrypted on alibitress, and data is also removed from AliExpress after 15 days of delivery confirmation.
More than 50+ orders are shipped to different customers, many of the customers are returning customers.
It's just pricing glitch, there is no money laundering or illegal activity going on. I assure you that.
Being a solo developer, I try to solve most of the problems, and to be honest, I improve a lot, and many people supported the idea.
Are you purchasing ordered items from original sellers and then shipping them to person who ordered from you, or you are only converting values from fiat to crypto with added fee?
If both you and seller can access personal information and delivery address, that is much higher risk of data leaks to happen in future.
I would pay more attention to this, and hire few more helpers to take care of bugs and issues.
I also agree, that pricing is 20-30% high than the original price, and I'm working on it to decrease it to optimal price.
Can you tell us how many people are actually using your website?
If you want to increase profit you need to reduce fees or offer some other advantages and discounts for paying with Bitcoin.
