Can you please tell me if this is possible:
1. I would like my eCommerce shop to have standard prices on display for non-members
2. I would like my monthly paying members to be able to order custom bundles with set quantities based on their membership tier - i.e. Membership Price Plan A allows you to select and order 3 'free' items per month that you can choose from a catalogue of 50+ items, Price plan B allows you to order 5 'free' items per month etc
3. If you try to request more than your bundle/price plan allows, you will be blocked/warned from doing so.
Is this possible with member mouse or will I need a custom build?
MemberMouse can help you with the 1st step right out of the box. That said, for your second and 3rd parts of your setup, you would indeed need a custom build. We have many customers that have found help getting their exact custom needs met by working with with a MemberMouse Qualified contractor. you can see that full list of implementation partners here: https://support.membermouse.com/support/solutions/articles/9000020324-implementation-partners.
