You don't handle this as an objection because it is not. You acknowledge the statement and proceed with your very best presentation with emphasis on building a relationship and creating a buying experience that will nullify the prospect's intent to continue the buying process elsewhere.
In short, you sell--and sell well. The fact that you are dealing with an up front individual actually makes your job easier. Put on your best effort and the wall will fall down. Your very achievable goal is for the prospect to reach a point where he/she now believes that a bettter offer or better person or better company is NOT going to be found elsewhere. In most cases, if that is achieved, the sale will be made.
