Amazons membership does not seem to recognize the new jagex accounts. Ive had no problems with this until changing to the jagex account. Will the product be updated or is this just being discontinued?
Someone asked this question on reddit. Here is the URL: https://www.reddit.com/r/runescape/comments/155qisr/is_it_possible_to_link_a_jagex_account_to_amazon/
Though it doesn't sound like it is functional.
However, once linked, you should be able to pay through Amazon for that character.
