How do you pick the products to sell? Can you share the store you're working on?
I had a few other stores before this that didn't sell well at all, and I have to say that's because I just didn't know the products, or what the end users really wanted/needed/cared about.
Great ways to pick products: - Terapeak (http://www.terapeak.com/), but this is paid - eBay completed listings - Or most simple (and what I use) -- once you know your products, search AliExpress and sort by "best-selling". That's my go-to.
Feel free to check my store for ideas (or if you want to buy something!). URL is: http://modshop.guitars/
Last question, you send directly from aliexpress to your clients right? Does it not bother you, your clients receiving packages coming from a different store than expected and with a Chinese address?
Oberlo (the drop shipping service) does have an email system that lets you track the package on its journey and see where it is shipping from, after an order is placed. So it's not unexpected that the address is Chinese.
Most of the vendors actually do a good job on the packaging/presentation, but it's advisable to try each vendor's products (even something cheap), so you know what kind of standards they have. Some are very good, others are poor. You can also leave the vendor an automated message when you order about how to package.
There are certainly faster shipping options from HK and China that aren't overly more expensive that you could get them to use or provide your own account given enough volume.
