enquiry + make an offer bid system

an add-on to your Enquiry Button feature, a make an offer option.

On the PDP, I want the Enquire button and a make an offer button that would open a bid flow. This would be shop specific, not globally on all shops on my site. eg.

• Shop A has enquire and make an offer button.

• Shop B has enquire and add to cart button.

make an offer flow:

1. -use enters an offer amount for the artwork

2. -Submit it to me directly

3. - I could then accept, or counter the offer (ideally via email or a simple backend workflow)
