why not use `if (promotions.getText().contains("½")) { return promotions; }`? — javaguest, Oct 15 '15 at 16:53

½ is \u00BD

Therefore this should work

if (promotions.getText().contains("\u00BD")) {

Try this:

if (promotions.getText().contains("\u00BD"))
{ 
    return promotions;
}

While this may theoretically answer the question, it's not really a good answer, since it doesn't teach the OP. Instead it gives an alternative solution without explanation. This will usually lead to OP not learning, and coming back for asking a new question when a similar problem occurs. Would you mind adding some explanation? – Vogel612 Oct 16 '15 at 10:36
