Can't pick a payment option

[EDCasper]

I keep trying to purchase a knife listed for sale, and when I get to the last step to pick a payment option, I keep getting an error message, for every option I choose it just will not work. Been trying throughout the whole day but can't seem to get it to work. I tried it while logged in, and also as a guest, same result. Is there anything I can do? Any help is appreciated

Hey EDC!
Great handle you have there!
You could try sending the seller a message through the listing, or contacting the admins here from the bottom of every page, best of luck, and to AAPK!

I caught your email about this yesterday. I suspect you received reply email. If not, please let me know.
