set amount

Hi there!

Can you please provide us more details about what you want to achieve exactly? I tried to purchase 1000 units of that product in your site and I get them all added to the cart.

If what you’re asking for is to force your customers to select a min/max number of units or to increase the units by a multiplier (for example to only allow them to pucrhase 1000, 2000, 3000, etc units), you’ll need to use a customization or an additional plugin to achieve it.

For example, I’d suggest you to take a look at WooCommerce Min/Max Quantities plugin or to search for any alternatives in the official WordPress.org plugins repository.

I hope it helps!
