Restrict reordering of products

-- Joomla version -- : 3.8
-- PHP version -- : 7

Dear All,

We wish to sell digital courses. One customer should be able to purchase the product/course only once.
If he/she tries to add the same product to the cart, it should not happen and should display a message.
How to achieve this ?
Any help in this regard would be highly appreciated.

Thanks and Regards

Hi,

You can use the Products>Limits system of HikaShop Essential and HikaShop Business for that.
You would have to create one limit for each product with a quantity value of 1, the period set to "forever" and the product selected in the "products" setting, and the order statuses you wish to take into account for the limitation.

is there a way, that a customer could buy only once but still pick what ever quantity he need that one time? kinda like a limitation not on the quantity entered but on the product selection instead?

Hi,

There is no such option in the limit system.
I'm afraid that would require some development.
