Which is more effective: a specialty store offering specific types of products that work well together within a chosen niche, or a mega store providing a wide range of products within that same niche?

A distributor I onboarded has a product line that includes nearly 1,000 products, spanning different brands and price ranges, from low-ticket items meant for bulk purchases to high-ticket products. Should I add all of these to my website?

do i need a DUNS and TIN number if im not located in usa?

*What is the size of the company: Number of employees? Total revenue? *Please can you provide an estimate for a 1-year order quantity? Can someone help me with what type of answers would be the best to respond to the supplier I'm new to high ticket dropshipping and have not made sales yet. Thank you.

if suppliers ask about my sales, but i haven’t gotten any sales yet, how should i respond to this?
