Givens Violins offers, to the original purchaser, a 100% trade-in on instruments and bows. The trade-in item can be used to acquire another instrument or bow of greater or equal value. Only one trade is allowed per item purchased, trading a bow for a bow, a violin for a violin, etc. The trade-in credit is calculated using the original invoice price of the item traded, minus a portion of the cost of strings, repairs and maintenance. If there is significant damage there also may be a deduction for resultant depreciation to value.
