Been in e-commerce since 2014 using companies like Gearbubble, Viralstyle, Represent, and Teespring. Selling through Shopify since 2016. Merch by Amazon since 2017. I can help you if you're getting started or want to know where to begin.
I've been selling t-shirts since March of 2014. Since then I've done over a million dollars in revenue across different POD platforms. I also now have a Shopify store selling physical products that currently has done over $1 million in gross revenue. I can talk about how to get started if you're a beginner.
If you're just starting out with Merch by Amazon, I can help you avoid many beginners mistakes and share my experience on selling t-shirts on Amazon in their Merch program. If you don't know what Merch is it's Amazon's print on demand platform for t-shirts.
