[New Furniture] Kristin Purchased $2,000 Worth of Furniture from Solid

[New Furniture] Kristin purchased $2,000 worth of furniture from Solid Wood Furniture. Through an arrangement with Solid Wood, Kristin financed the purchase through a financing company called Let Us Help You. Twenty-nine days after the goods were delivered to her, Kristin had a disagreement with Let Us Help You regarding the amount of interest she would be required to pay. She notified Solid Wood on that day that she was rejecting the goods. Solid Wood claimed that she did not properly reject the furniture and also that she failed to act in good faith, an obligation imposed equally on all parties to a transaction. Kristin says that she properly rejected; that, although the UCC imposes no duty of good faith, she acted in good faith; and that, in any event, she had an absolute right to return the goods.
