Pay what you can

The option’s price becomes a suggestion, and you set the least a member may choose, which can be zero.

Tick Pay what you can on an option. The member sees the suggested amount and types what they can, at least the minimum you set. Leaving it blank pays the suggestion.

If the minimum is zero and a member chooses nothing, they are a member at once and the payment is recorded as zero, with a note. The report shows how many paid what they could and what they paid against the suggestion.

Discount codes and parts are not used with pay what you can, because the member already chooses the amount.
