I've previously used Sellix, around 2-3 years back. And knowing the fact how well-positioned they are in the ecommerce market, I was shocked to see them here in AppSumo. Needless to say, I jumped in and bought the deal immediately.

Initially, we had a small hickup with our signup process. Their security or fraud detection system was blocking our email address, possibly because we were using our not so old business domain. However, after raising a ticket with their support team it was fixed without any further complications. Considering I am from a different timezone to their support team, they responded and fixed the signup issue pretty fast.

I was pretty impressed to see how far they've come since I last used their platform. The dashboard has been re-designed, new customization features, several payment methods, fraud detection system, are few of the things I noticed instantly. All I can say is, it seems they were constantly developing and adding new features in last couple of years.

If you are into selling digital products, I am pretty sure you've already heard of Sellix and it's a no-brainer, do not miss this deal.

Some plus points:
- easily list and sell license keys of your app/software
- sell serial keys and let users download apps/files upon purchase
- several payment options, including crypto
- you have the abiltiy to decide how many confirmations required for crypto transactions, before the sale is marked completed
- fraud detection system. Avoid dodgy customers
- manage/see paypal disputes from within the dashboard (i haven't used this yet)
- decent customization features. you can also use your own domain for your online storefront
- you can make certain products public or private
- no fees on a generous limit of annual revenue
- and as I was writing this review, I believe they've increased the cloud storage limit to 1TB for AppSumo users.

Things that I'd like them to improve on:
- though bulk upload can be done via their API, I'd like to see this feature in their dashboard user interface
- ability to delete shops from the dashboard. I wasn't able to find any options to do so in the user interface. I think we have to raise a support ticket to delete old/un-used shops. Though, I can see why this option is not there in the dashboard. Sellers/merchants can mis-use this feature for reasons I don't want to post here.

Overall, its an easy 5/5 tacos from me. In my opinion, this lifetime deal is priced amazingly low for the feature set Sellix provide and especially when compared to the monthly fees charged by their competitiors as well as Sellix themselves.
