The process for buying items and runescape gold is very similar to selling on the Grand Exchange. First access your Grand Exchange offer screen, and then click on the Buy icon in one of the empty slots.
You’ll next see a Buy Offer window that looks a lot like the Sell Offer window from the previous section. Also, a Grand Exchange Item Search box will appear in the game message area in the lower left corner of your screen. Here, you can type in the name or the partial name of the item you want to buy and the game will search for all possible matches to that name. For example, if we type in talisman, we get a list of all possible items that contain the word talisman that can be traded through the GE.
Once you’ve located the item you want to buy in the search box, click on it and it will appear in the Buy Offer window. As with selling items, you can adjust the price, depending on how much you are willing to pay, to within 5% below or above the current market price. Before trying to buy an item, you must have the gp needed to make the transaction in your inventory. That money will automatically be deducted from you and used to pay for the item if it is available. If you happen to offer more for an item than what someone else is selling it for, you’ll get that extra gp back when the trade is completed.
When you’re ready to make the buying offer, click on the Confirm Offer icon. If you think the item is too expensive or if you’ve just changed your mind about making the purchase, you can exit the screen by clicking on the X in the upper right corner or the white back arrow in the lower left corner.
Just like with selling items, you don’t have to wait around for the trade to be finalized. In fact, if you’re trying to buy rare items, it may take quite a bit of time for this transaction to occur. Instead, you can continue to go about your business and you’ll be notified when your offer has been updated. Then you collect your purchase and any leftover gp from the original offer at any bank in Runescape.
