show list coupons in frontend to user

-- HikaShop version -- : 2.6.2
-- Joomla version -- : 3.5.1

hi,
how to show list all coupons to user in fronend?

Hi,

There is no automatic system for that. You would have to create a Joomla article and write the coupon codes in it manually.
Or develop a custom Joomla content tag plugin to generate such list and be able to include the corresponding tag in a Joomla article. But you'll need to be a developer to be able to do that.
