The one that seems acceptable to them is to list one cheap part for the listing, along with variations of the full device. That way it looks like the lowest price in search results, but when you click it, the selected variation is the cheap part.

This practice is so widespread on Ali that finding the best price/seller that is likely to get the item to you balance is ridiculously time consuming, a lot of the time the cheap item is something barely related to the item you’re searching for. It also seems to be creeping into Amazon at the moment!
