Hi,
So you're talking about a graded payment ; a spread price.
The "share price" seems more related to trading (
en.wikipedia.org/wiki/Share_price
).
But in any case ; to display such thing means you have a payment method compatible with that kind of payment.
And there are rules to display such thing ; you can't say that every product will have a 10 step payment...
About the shipping estimation ; that feature is not yet available in HikaShop but we are working on it for a future release.
The development is still in progress.
