Tired of dealing with physical product delivery problems and low profit margin
Guess what ? I got tired of digital products (as Paypal, etc hate digital virtual non-physical products) and I moved to physical products. Not all physical products have low margins. And in physical products, you need to select products which women or old people use and target US, because women and old people tend to make less or almost no comparison research prior to buying, so they usually do not do a price comparison research. If you know which platforms to sell such products to the audience I mentioned (women & old people), you can even sell products costing you US$20 for US$60, whereas in other websites (ebay, etc) it will be available for US$30. And I no longer pay for ads as far as my dropshipping products go (for other uses APART from dropshipping, I use Google Ads mostly, but NOT for my dropshipping product's promotions), I use certain known social media platforms, BUT in very unique ways (with some twists).
In dropshipping, there has to be a deep strategy used, otherwise you will be stuck within the competition.
And about delivery delays : that also depends on which dropshipper you are using. But, yes, there could be delivery delays, however with a good dropshipper, delivery delays are to the minimum and in such cases, have a good customer follow-up system in place, apologizing to the buyer, offering a discount code for that buyer's next purchase, etc.
People sometimes say that dropshipping is dead or is dying. It is not ; more and more people are buying stuff online and most of the online sellers have dropshippers in their chain. What is now competitive is that everyone still prefers to use (paid) Google Ads, Facebook Ads, for dropshipping, which also costs money. As I mentioned above, one can use for free various social media platforms to make sales, BUT with unique twists. As the saying goes, avoid doing different things, rather do things differently.
