Central Hardware Supply

Sam Gillespie, owner of Central Hardware Supply, was referred to you by a mutual friend. Gillespie was thinking of dropping two of his product suppliers of home-building supplies. "The sale should be guaranteed" your friend had stated.

Your friend's information was correct, and your presentation to Gillespie convinces you that he will benefit from buying from you. He comments as you conclude the presentation, "Looks like your product will solve our problem. I'd like to think this over, however. Could you call me tomorrow or the next day?"

Question:

How should you handle this situation?
