trying to figure out if this plug in is for me

I don’t think this plug-in will achieve what you’re trying to do. It doesn’t store card information, or retrieve saved cards.

Our workaround to a similar situation is to take the order and authorize the card for an amount +10% (or whatever the maximum cost would be). After completing the invoice and making the adjustment, we can capture the exact amount. The product someone purchases is described as “price by weight” and price will be adjusted after weight. Alternatively with some custom code or checkout customization, you could add a “product” at checkout that with disclosure to the customer then authorizes an amount (say, $10) higher than the invoice total so you can capture the exact amount after adjustments. It’s a little convoluted but it’s the result of a reasonable limitation of credit card processors.

This plugin does support authorizing a charge without capturing, but banks will not allow you to capture more than the amount authorized. You can authorize more than the usual price and then capture less. However, this plugin does not currently support capturing previously authorized charges, so you would only be able to use this plugin for the initial authorization, and you would then have to capture the charge from your payment gateway dashboard.

@oomatty thank you for your reply. What are you selling? Can I see your site? How do I capture a slightly higher amount and then only charge the exact amount? Thank you!

You can simply enter the higher charge amount into the Amount field. Then visit your payment gateway dashboard and capture the exact amount. The instructions for the capturing step depends on which gateway you use.
