Check the listing for details. Promaster Off-Camera TTL Flash Extension Cord for Canon 8144. Condition: Open box. Listed at 29.00 USD. Looks new in packet but I wasn't the original owner so it conceivably might have been put back. The packet has some wear. This is not the latest version of this product. It says it is for Canon digital and traditional SLRs, but perhaps it doesn't support the newest ones - just my guess. Combining Orders We are happy to combine orders to save shipping costs, but we can only do this if you first add the items to your cart and then choose Request Invoice. This only works on the browser version, not on the Ebay app. Once you have paid for an item it can no longer be combined. Shipping We ship within 5 business days but usually sooner. We pack very carefully. If you are overseas and using a forwarder, please be aware that we can only track as far as the original U.S. destination and our responsibility ends when it is delivered to that address.
