I never heard of it, but I would do a lot of research, before using it or anything. The best place to check if they sell things, is the Better Business Burbeau. People leave reviews and they also rate the site.
For example with the BBB I was being charged a hefty fine of $70 a month to a weird website, some TV one, and I checked it out and it was a scam. I had to call the website just to get my money back and it was super hard. I lost $500 because I didn't catch it soon enough.
Now not all websites are scams, you just have to becareful, watch for those who ask for money, if they ask money for a spell, which would be more powerful if you do it yourself, is probably a scam. If they only sell magical items (tarot, wands, etc) then it may or may not be legit.
I've been scammed many times through websites, even amazon, but luckily amazon has great customer service.
So becareful, hope this helped a bit :)
