LPT: While shopping online, always abandon you cart at least for a day, there's a possibility to get a discount.

Not all stores do this, but all platforms (Shopify, Prestashop, Magento, etc.) have the functionality to automatically offer discounts to abandoned orders. You won't lose anything by trying and is possible to obtain at least a 10% discount. Sometimes the offer triggers immediately while leaving the site, sometimes they send an email hours later.

Even if you don't get the discount, is a good habit, it gives you time to reconsider and avoid an impulsive buy.
