Hi,
Edit your menu item via the Joomla menu manager. There, under the "products options" tab, you'll find the setting "Which price" where you can configure how you want the prices to appear on the listing when there are several prices available for a product. It defaults to "cheapest price", but you can have a range.
Then you can use translation overrides to add text before or after the price on the listing:
www.hikashop.com/download/languages.html#modify
For example, if you display a range, you can add such translation override:
PRICE_BEGINNING_1=" up to "
And you'll get something like that on the listing:
5.95€ up to 73.50€
