Haha should I consider myself lucky to launch their thread here or maybe a sig campaign in future? I have seen few other platforms offering such services but always found some restrictions, not all can be used worldwide. But this one is soo smooth that why try bringing them here, and here we are. Tell you friends if they need free virtual card. I have a campaign for that.

However, we like to see their ads on the forum through signature campaigns. I believe this way they will get a lot of customers from this forum, and it will build trust for them. Since you have communication with them, you may discuss the benefits of the campaign and convince them.
