I was able to grab the Pink CitH Deck this week. I used Chrome autofill. My address is already saved so all I had to do was let it fill in my card and I typed CVV. Last week (CDG AF1), I got declined payment because I was using the Bolt extension so that might be dead now...
Also, my mom's address has been banned on/off for about a year now. I have been ordering to that address for about 8 years and I can say it is definitely blacklisted (at least during 11-11:15am on Thurs). It's probably because I used to buy two of the same items (just tweaked the address a bit). It's not my card because my bro tries to order and gets declined so that's how I know it's an address ban.
Last week, my bro went for the Field Jacket during drop time and was getting declined, I checked out for him at 11:16am, it went through.
Sooo for those getting declined, are you using any autofill (chrome, bolt, fillr or others)? It could be your card or address is banned. Try a different card with same address and if that doesn't work, try ordering something on the site 10-15 mins after the drop to see if it's an address issue. And if that's the issue, you just have to change your card to another address (super inconvenient I know).
