Any tips for increasing sales?
Make your listings fully optimized with relevant keywords.
Your products are over priced.
Price point sells, cheaper the better. If you cannot be the lowest price seller, then plan on dividing 20% of the prospective buyers among yourself and the other high priced sellers.
As @skeeter says, the market is over saturated with t-shirts. Unless you are selling something unique, I don’t think you will find buyers for regular t-shirts at $20. Maybe try including some popular memes or quotes to make them more appealing.
To sell your t-shirts on Amazon faster, focus on optimizing your product listings with high-quality images, keyword-rich descriptions, and competitive pricing. Additionally, promoting your products through social media, using Amazon Ads, and leveraging tools like Amazon SEO can help boost visibility. For a wider reach and more unique designs, consider partnering with platforms like https://dotrumpstore.com/, which specialize in niche markets and can help increase your sales.
