Differently from many other suppliers integrated in ApiDrop, Aliexpress does not offer an API endpoint that permits us to retrieve product's prices programmatically.
For this reason, scraping is the only way to obtain info about products, prices, orders etc... but we face many challenges to keep everything aligned.
One of the most common issues is the price misalignment due to a promotion that Aliexpress offers by default to every new or guest customer and that basically show off an heavy discounted price instead of a regular price.
So when you add that product to your Aliexpress cart, if you are not a newly register customer, it will have a different prices.
We are working around the clock to find a scalable solution to this problem that fortunately happen only on 0.3% of the entire catalog.
