This is specially truth if you plan ahead of time. So instead of buying from whatever offer exists on the market, create buy offers with better prices. Also, it's worth keeping an eye on the items to notice eventual price drops and take advantage of them to make up a stash of useful items.
Also, sometimes it's worth to use 4 Gold Tokens to get the items for the Intricate Imbuements and other one, since the last items are usually a small amount and not necessarily expensive (e.g. Some Grimeleech Wings). This is also a good idea if you have a lot of Gold Tokens since you'll avoid dealing with the hassle of trying to sell them for a good price.
