Find a seller from whom to purchase your ArcheAge gold. There are many sellers on the Internet and sometimes you will see them advertising in-game in the Trade Chat channel.
Research the seller you wish to use to see if it is reliable and compare prices. Because it is against the game’s TOS to buy and sell cheap ArcheAge gold, there are few repercussions for sellers who don’t deliver what they’ve promised. Search for reviews of different sellers and go with the one who has the best reviews.
Make a small initial purchase. You don’t want to spend a lot of money only to find out that the seller has scammed you and has no intention of delivering the gold. Buy the smallest amount it has to offer to gauge how reliable it is. The seller will want to know what server you are on, what faction you play and what your character’s name is. The seller may also require an automated phone verification.
Pay with Paypal or another secure method that shields your credit card information. Never give your credit card or bank account information directly to a gold seller.
Wait for the seller to make delivery. The gold should be delivered to your in-game mailbox. Most gold sellers have a timetable on their website that shows an estimate of how long it takes to deliver gold to each server and faction. If the seller delivers the gold on time, then it is probably safe to make a larger purchase from the site.
