Last week I purchased two bottles of syntrans and two bottles of syntrax off eBay from a seller called smeagold-2008. They sent 3 of the 4 out and are denying not sending the fourth one. I've been down the useless ebay ladder and got nowhere. After several attempts with the seller to resolve the issue I've given up! There the cheapest on ebay but don't be tempted to buy. Pay a little more and hopefully you'll get what you ordered!
Cheers
