of the decimal point. The price can be negative (to give a discount)
		by inserting a dash/hyphen/minus sign between the pipe characters and
		the first digit.</p>
	<p>If you want a particular option to have no price attached to it (only some
		options cost more), you can either set the price to 0.00 (a price of
		0.00 will be displayed) or follow the pipe characters with a dash/hyphen
		(no price will be displayed). If any option in the field has a price, <em>all</em> lines
		must have the pipe characters at the end (whether there is a price attatched
		or not). If any value has omitted the pipe characters, all subsequent
		prices will be shifted up one value.</p>
	<p>Do not include a currency symbol &#150; it will be added automatically based
		on settings on the <em>General Settings</em> page.</p>
