That site seems to be affiliated with Pub Tricks which is a huge rip off. Their can trick also looks quite similar to a Sankey effect, along with many others that are identical to other effects on the market. E.g. Saw by Sean Fields.
I saw it when I was starting in magic. I think This and That led me to the site. I don't really know what it is like, since I never really go on it. I'm not much help here.
