Hi, Generally the most popular products are very saturated especially in the dropship arena. You would want to steer clear of the hot items and sell items that is less popular.
Dropshipping has become so hard especially for ebay sellers as literally every drop ship supplier sells the exact same stuff. Meaning you have 50,000 other dropshippers competing against each other and wholesalers beating them to the puch with lower price products.
If you have the capital at all to buy in small bulk, I would recommend you avoid dropshipping if you can.
