"If you are not able to afford the XXX, there are less expensive models in the range."<br/><br/>Official answer:<br/><br/>"<u>Should</u> you not be able to afford the XXX, there are less expensive models in the range."<br/><br/>Can I write:<br/><br/>"<u>Were</u> you not able to afford the XXX, there are less expensive models in the range."<br/><br/>Thanks.
