Hi,
Yes. You could use a translation override :
www.hikashop.com/download/languages.html#modify
At the beginning of HikaShop's translation file, you can see:
PRICE_BEGINNING=""
PRICE_BEFORE_ORIG=" ("
PRICE_AFTER_ORIG=") "
PRICE_DISCOUNT_START=""
PRICE_DISCOUNT_END=""
PRICE_BEFORE_TAX=" ("
PRICE_AFTER_TAX=" excl VAT) "
PRICE_END=""
FREE_PRICE="Free"
PRICE_SEPARATOR="<br/>"
PER_UNIT_AT_LEAST_X_BOUGHT=" per unit for buying at least %s"
PER_UNIT=" each"
So for example PRICE_END is empty by default and goes at the end of all the product prices displayed by HikaShop.
