I have used their service once, I found globalshopaholics through random searching on google. The best part is that their process is highly automated and they give you options of different shippers. They also provide consolidation of different shipment, if needed and they can buy for you as well if need be, but it's a paid service.
The website is not that customer friendly. I wasted alot of time understanding the website, I think they should upload some videos as to how to use their website.
Their customer service is a bit slow but I think because of Covid-19 every business is affected. But I personally think they should work on it. Overall I had a good experience for first timer.
P.S. I have updated my comment, since initially I didn't get a good response from there support. But eventually they apologized and explained me the reason.
