SCAM site. They have four (4) books I wrote on their website. They are all obviously pirated being poorly scanned library books (one of them has the library logo blanked out). I asked them to remove one which they did but soon after they reloaded it. They sourced my books from Libgen which proves they are a shonk.
Books are cheap because they are STOLEN.
If you read down the reviews below you see they have pirated a heap of books.
