I saw some stores using a variation of this.
Basically, a customer adds a product in their cart and this message pops up above it, saying how the product is in demand and they have 10 minutes to buy the respective product, and if they fail to do so the cart automatically refreshes.
How do I implement this in my store?
Thanks!
Sorry for the potentially stupid question/explanation, I’m just new to e-commerce/shopify 
Hello @alexc3301

You can achieve this using the iCart upsell app. You need to check the “Enable Cart Urgency” option as shown below image.

Hey, @alexc3301
What you’re looking for is known as a countdown cart timer. There are a variety of these apps available in our app store. I’ve compiled a list of some potential options for you below:
With that said, is there a particular reason you want customers to potentially lose out on the items after 10 minutes has elapsed? If there is anything else I can help you with, please let me know.
Is there a way that the countdown apps would also reserve stock for unique items?
i.e. 1 item in stock, once customer adds to the cart, it is no longer possible for any other site visitors to add to cart?
We need this as well! Lots of cart timers are out there, but nothing that prevents another shopper from placing the unique item into their cart for the reserve timer.
