Remember, you'll need to budget for ads (Facebook or Google, which can be costly). You'll also need to create a website, target a niche market, analyze the competition (using paid tools), and find reliable suppliers. Be prepared to handle customer complaints and returns, as well as long shipping times (8-20 days if you use platforms like AliExpress, unless you're selling digital products). While many try and fail, there are those who make a lot of money from it. The key is thorough research and creativity—don’t start spending until you've done your homework.
