I have the highest bid on this product http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170662473240&category=33034&_trksid=p5197.c0.m619 and I want to ask.Is the item been sent to me immediately after the remaining time passes by ? By now it is 5 days and 2 hours.Or I have to click "Buy now" like on any other product.I am asking this because I'm a noob at ebay but I have the highest bid for this guitar and a still don't have the money.Someone please give me an answer.
