Hi, I’ve been trying to buy 3 codes for the last 3 hours using my Mastercard, but I keep receiving this error: “There was a problem processing the Stripe transaction.”

I also want to use a 10% discount coupon, which reduces the total price from $177 to $159.30.

I’m trying to contact AppSumo support, but the live chat is currently not available.

Could you please help me complete the purchase or tell me what I can do to resolve this payment issue?

Thank you.
