I was excited to have my 2 characters wed only to find out that the required 1 pcs of Marriage Covenant cost US$5 each

You could buy 7 day VIP for 200 WarpPortal Energy for the account or accounts that need it to get married. If it is two accounts that need them then you will be looking at 400 WarpPortal Energy.
