How can I add a quantity button to my product page?

Hi @Auraandstones hope you are doing well. If you are facing the same issue kindly try Extendons Quantity Selector. With the help of Shopify Minimum Order Quantity App You can create and customize a button for increase or decrease, and replace the old-looking options with a button for plus or minus. Choose from the captivating designs and customize the background and text colors. The buttons can be placed on product, shop, and cart pages to ensure users take advantage of them. It is also possible to set up quantity increments so that shoppers can shop in different sets. Define a quantity range by adding minimum and maximum limits. An alert message can be displayed if the selection does not fall within the quantity range.
