Our client needs to give the option to the customers to buy certain products in the decimal quantities. i.e. the customers can buy in periods on 0.25. (0.25, 0.50, 0.75, 1, 1.25....... )
Enabled the option Qty Uses Decimals from the admin panel, when i go to the frontend and add a point its gives me the following message
You can buy this product only in quantities of 1 at a time.
If you know about patch or any extension, that would help
