Hello.
I'm getting a problem with the membership function of the plugin, seems to be a bug:
I creat a few groups, with different discounts: 20%, 50% and 100% flat discount.
Everything works well, and all users are able to choose their promotional options (premium, highlight, republish, mov to top). But users with the 100% discount plan can't make the checkout and publish their promotions, as there is no "finalize" button in the cart.
Can you check it, please?
Thank you

@atomo
100% discount cannot be available as that would mean free checkout that is not supported by plugin.

@MB Themes
Yes, and that is what the plugin needs: a free checkout button.
Because everything else works perfect: admins can create 100% discount packs, and users can choose its promotions, they just can't complete the checkout. So this is not exactly a non-supported function, but a missing one.
I beg your attention for this.
Thanks.

@atomo
There is no free button and there are no plans to have free button.

@MB Themes
But there should be.
I continue to say this is a missing function, since the plugin allows ALL the steps to create a total discount. Except the last one.
So, up to a 99% discount, it works. But not with 100. It's ridiculous.
As it stands, the plugin only serves half of what is proposed. And it's pity. 

@atomo
Name of plugin is "Osclass Pay", not "Osclass Free-to-pay" or anything like that. You cannot checkout with 0 amount and this is not going to be changed.

@MB Themes
As you wish, it's your plugin.
But what is said on it's page suggests something else:
«User groups - create as many groups as you need, there is no limit. You can define group name and description, price for selected period (i.e. $ 20 for 30 days), setup flat discount for item promotions...»
Well, in my land, a flat discount can go from 1 to 100%. But maybe my arithmetic is different...
Regards.
