What can i do i have 22.9m and i am trying to buy a bandos godsword and no won sells it for that low i have been waiting to get it for days and no one will sell it

You have 3 options here
1) wait and hope the price for a BGS drops so you can buy it at a lower price
2) make more money so you can buy it at a higher price
3) dont buy it all together because it is a crappy sword anyways (you train faster with a whip + rune defender/DFS)
