Sorry, I disagree. It does not say pair at all. https://www.trademe.co.nz/a/motors/car-parts-accessories/tools-repair-kits/jacks/listing/6194948810 My first search was via Mac, the listing said 2x car ramps, buy now $78.90. When clicked on that became $78.90 each. Each in English means one ramp. It should have said per pair, if it actually meant 2 for $78.90. In the mobile app, it says per item. Which is still not clear. Is the item the 2 ramps or just one. In any case, it cost them a sale. That's Trade Me's responsibilty for not insisting on clarity.
I've just been searching for car ramps. Most of the listings show ramps x 2, or a pair of ramps, and the buy now price. When you go into the listing it then says the price is per each. How/why is this being allowed?
