How do you find wholesalers in Europe?

Hi Guys i am doing amazon fba wholesale i tried many times to buy branded products but I can’t get because many wholesalers in Europe told me we can’t sell it to you you should buy it from our partners so their partners will sell them too expensive and don’t provide the invoice,

So could someone tell me or show me some direction from whom should i buy branded products and where , i still haven’t find any product to buy and sell in Europe thanks ?

Have you tried reaching out to authorized distributors or resellers? They might have the branded products you’re looking for.
