There's a good way to do this and a bad way. One good way is to make the link text specific to a unique product. If 'Sony 30" XXX-700' was used as the link text, instead of 30" Monitor it would be a detailed link telling the user that they're going to a page specific to that item. Another option is to put all your referral links at the bottom of the post and highlight some of the best 30" monitors to choose from. Same for all the other product types you linked to. The bad way is to link a nondescript phrase like 30" Monitor to a random 30" monitor on Amazon. It doesn't provide any basis to understand why you linked to that specific monitor. Are you recommending that monitor specifically? Is that the only one out there? Etc.
