Never really got how aliexpress works but I tried buying the caps and it took a solid 30 minutes of fighting a really broken website. It was sunk cost fallacy the entire way. Finally after showing the most "mechanical sympathy" toward this broken site I could muster I got to check out which was the most broken and weird flow I think I have ever seen. Finally, breathed a sigh of relief hitting Place Order.

Nope. It wants amex to send me a whole new code to my email and this and that and this and that. Now I'm transmitting codes from @welcome.americanexpress.com on to aliexpress and I'm like nope I'm out.

So, still looking. Found one that matches on amazon and then lost it. Search continues.
