This is just trash. All they git is some sort of book catalogue. they actually don’t have books handy. they might take months together. each tome you call they say, books are arriving today and they will ship them today, which they never do, if you sound angry on phone, call will be transferred to their lady employees who only know how to say "hello", irrespective of how loud you speak, you will keep on hearing hello hello.
My kind advice, please don’t buy books from them, if your local vendor don’t have stock just wait for a week or two. he will sure get them for you. Books4U will eat your time as well as the postage charges as well. you will also loose your phone bills calling 0562-2527783.
