Ads in your Instagram feed may be irksome, but wouldn't it be nice if you could at least find out how much it would cost to buy those sweet shoes or stylish bags? Instagram sure does. It's starting to roll out shopping tags that identify the products in ads. Tap a button and you'll see the basic details of products in a photo ad; tap those products and you'll get both more details as well as links to visit their store pages on the web. You can't buy goods directly from Instagram right now (possibly a good thing), but you also don't have to scrounge through a retailer's website just to find what you saw a moment ago.
