I've never used it, seems to be too new yet to have gained any sort of reputation good or bad, so that in itself is a bit risky compared to buying from somewhere that's well established and carries customer buyer reviews (like Amazon, for example) from which you can make an informed decision.
So in that light I wouldn't buy from them just yet as there's no customer feedback (and there's no better way from which to make your decision).
Unlike you. I don't think it's a scam, it's simply too soon to recommend it.
