RE: #1 – I understand that only one pack can be purchased at a time (e.g. one checkout session at a time), but can a seller purchase one pack (with recurring billing), then purchase another pack (with separate recurring billing) in a different checkout session?
We want to allow sellers to start selling their products for free, but then purchase one or two premium subscriptions. We then display their names in a different part of the site (giving them more exposure) based on the premium subscriptions they have purchased.
As always, thanks for your awesome WordPress work! You guys are the best I know!
