I’ve experimented with multiple platforms over the years, from eBay auctions to Shopify stores. What I found interesting is how niche platforms can outperform the big names if your product fits their audience. I recently started testing print-on-demand setups, and gearbubble came up as a suggested option. It’s pretty hands-off once set up, and integrates with marketplaces like Etsy. The interface is a bit dated, but the fulfillment side works smoothly.
