Your idea is against eBay's Link Policy[1] and eBay actively remove listings (and in some cases limit users ability to sell on eBay) as their Policy states if you link to non-eBay sites where other items are offered for sale. Likewise, adding a phrase which may even suggest purchasing for less on another marketplace will probably lead to them editing or removing the listing from eBay as well. If you are going to do that idea then, do it as a marketing campaign, not on eBay listings.
