Shopping Cart Freezes UIKIT

I’ve been trying to purchase UIKIT and the shopping cart keeps “locking up”.
I tried at different locations and wifi networks. No luck.

Love to purchase product, but it looks like its not possible.

Where does it freeze?

I’m able to hit the purchase button and it pops up asking for nane and email:

Could not reproduce an error here either, but here goes the direct buy link:

That worked without any problems! Thanks for the link.

Just to be sure, I tried again, and the “cart” view still locks up, after filling in all the data and right before entering payment. I’m using the latest Safari and Catalina 10.15.3

Yes, then, the NEXT step locks up the UI…
