We have 2 web addresses for the online "The CCA Logo Store" - store.ccgtcc.com (the short / custom version we created) and also https://the-cca-logo-store.printify.me. This longer name is assigned to us by Printify when we opened the store.

For some reason, when entering the store using store.ccgtcc.com, there's a glitch so that your (correct) credit card info is interpreted as a "payment error" and it won't let you check out. I've reported the glitch but it likely will be a few days before it's working correctly.

In the meantime, just enter the online store at the longer web address and you should be able to check out just fine. I completed a transaction just a few minutes ago. Sorry for the glitch.

In summary, use the following web address for now:
https://the-cca-logo-store.printify.me
