Just got hit with Error 15

I was browsing pokemoncenter tropical shirts on my computer, then I got hit with error 15.

I contacted support with my phone browser, cuz it blocked my computer IP. They said:

"We are committed to providing a smooth purchasing experience for fans, and as a result, employ technology that helps get products into the hands of customers instead of bots. However, we’re aware that customers can sometimes be blocked unintentionally. We understand this inconvenience can be disappointing for fans and are actively working to limit these types of occurrences as much as possible.
 
At the same time, we are experiencing very high demand for our products and are working as quickly as possible and at maximum capacity to support this increased demand. Please note that newly released in-demand items generally sell out quickly.
 
That said, our team is unfortunately unable to lift these types of restrictions. We can only suggest checking back at a later date to see if you have regained access.
 
We appreciate your feedback and ongoing support, as we continue to implement fixes that provide a more seamless purchasing experience for customers in the future."

Uh... that's hella lame.
