RESOLVED: problem using Standard Payment for $0.00 order totals (via coupons)

[safire]

JM 3.8.5; VM 3.2.12; AwoCoupon 2.5.9.3; PHP 7.0x

I am using AwoCoupon for coupons and gift certificates. In the rare instance when an order total is $0.00 I've setup a VM standard payment to display as payment option. I configured it with these values:
Minimum Amount: 0
Maximum Amount: 0

The problem is this payment method is displaying even when total amount is over 0.  (selecting it will complete checkout without any payment needed.)

(I setup Paypal for Minimum Amount 0.01 and it correctly disappears when order total is 0.00)

If I setup VM standard payment with Maximum Amount: 0.01, then it is correctly hidden for orders over 0.01 but is unselectable. (Selecting it refreshes page and it reverts to unselected.)

I would appreciate any suggestions on how to get this working properly.

Have you try using
Maximum Amount: 0.001 ?
If Maximum is empty, it mean Do not check Maximum, so you see it for any prices

[safire]

yes, I've tried many amounts including 0.001.

I should have also mentioned that Offline Credit Card payment remains visible as a payment option even when total is 0.00 (I've contacted the developer of this.) If I can get Offline Credit Card payment hidden then the Standard payment option should be automatically selected and my problem solved.

Test with Maximum Amount: 1.00 if all other product have price over 1.00

I tested with 1.00, same behavior.

Hi, you can buy my plugin here https://shop.st42.fr/en/tools/shipment-rules.htm, i developped it for my own customer (having more features as core shipment) and added it in the shop in case you dont find a solution.

Resolved. I contacted developer of Offline Credit Card plugin. Plugin was updated to work as expected: when set to Minimum Amount 0.01, that payment option dissappears when cart total is 0.00. This left the Standard Payment option alone and pre-selected.
