I wanna buy a new license of sketchup pro, but error

I wanna buy a new license online of sketchup pro, but have some error.
The price is always $0.

Could someone help?
I use VISA or MASTERCARD

Are you purchasing from the main SketchUp site or a resellar? Take a screenshot and show us what you’re seeing.

main sketchup

I will try it again after 1hr

It still has the same error. alway pay $0

I just try to bug a new license using edge (all cookies cleared) but not successful.

I will try the old account (sketchup@plan-in.com)

I can buy a license using sketchup@plan-in.com. thanks
