Oberlo is a good option if you're using Aliexpress.
There are many benefits to using Aliexpress for dropshipping, and there are a lot of cons as well.
I've tried them, and I went back to the way I've always done business, through US manufacturers.
- Shipping times can be very long leading to complaints from customers.
- Even though products can be much cheaper (and there is no control over quality), the prices have definitely risen as it has become more popular.
- I've paid for epacket shipping to speed shipping times up, and sometimes the supplier has 'forgotten' to ship that way, and they pocket the extra cost, and I've had issues trying to get that money back. Too much wasted time.
- tracking isn't available until it hits the US, or outside of China.
There's other reasons, and I have a site that my customers appreciate knowing the products are manufactured in the US, not China, it attracts people. Some people have challenges with Chinese products and not supporting US made.
Also, as time goes on, eventually, the products will cost more then it's possible to create a good profit, so I don't see it as a sustainable, long term business. There are many things changing, and have changed with their laws in the past year, that are affecting doing business with them.
I'd rather develop relationships with people here, and offer products that you can't get overseas.
