What does this price mean?

This is the price (excluding shipping and handling fees) a seller has provided at which the same item, or one that is nearly identical to it, is being offered for sale, or has been offered for sale in the recent past. The price may be the seller's own price elsewhere, or another seller's price. The "off" amount and percentage simply signifies the calculated difference between the seller-provided price for the item elsewhere and the seller's price on eBay. If you have any questions related to the pricing and/or discount offered in a particular listing, please contact the seller for that listing.
