Is there any difference in US & UK marketplace in terms of online arbitrage?

Hello. A client reach out to me.

I’d like to ask from some Product Researcher for Amazon FBA in UK.

Is it possible to get atleast 10 qualified leads per day?

About Helium 10, is there a guarantee that there’s no repetition in every search?

I did Retail Arbitrage for US client. We used Keepa and Selleramp. We used a lot of techniques to source products.

Please let me know before i respond to my client. I’d appreciate any insights
