Is dropshipping still viable, and do US/EU suppliers matter?

The model still works, but the easy version does not: long shipping times and commodity products get punished by ad costs and refund rates. What aggregated operator reports consistently show is that domestic (US/EU) suppliers — faster delivery at a higher unit cost — convert better, refund less, and build repeat business. Treat dropshipping as product-market testing with real margins math, not as a passive-income shortcut.
