“Come Early.” That’s the advice for people who want to bring items for appraisal by Harry Rinker, host of HGTV’s “The Collector Inspector.” He’s making a return visit this weekend to the Greater Roanoke Home and Garden Show at the Roanoke Civic Center. Rinker will look at up to two items per person. Also making appearances will be Roger Hazard of A-&-E’s “Sell This House.” He’ll give advice on how to stage your home if you’re trying to sell it.
