Example - etsy showing $41.60 in shop and open up to find correct price of $36. In my shop I only had 3 such items, but daughters shop had several. To fix I opened up listing and resaved and that corrected it.
Been happening for a few days now.
There have been other Threads about this. Looks like another test (I'm not seeing it yet). But some listings display the item price including shipping (even if the Seller has shipping separate from item price). And for some reason, it doesn't affect all of a Seller's listings; rather, some of them.
You could try this if you want to. On the listings which are affected, go in and edit your price, typing the correct item price again. See if that changes the way it is displayed.
