Promotions and discounts are the most common promotion tools. There are many options: install the week's product or the day's product and sell it at a discounted price, arrange discounts in the morning or night, make a discount when paying by card or pick up - whatever you want. Do not be afraid that discounts will hit your profits. They will only increase your earnings with a competitive pricing policy. It would be best if you also pay attention to the SEO promotion of the online store. Keywords and tags will help raise your site search results and increase traffic.
