Swedechris, just a suggestion here, but perhaps you need to pick your words more carefully when dealing with people. When you say, "I am ready to buy," you may be thinking, "When I find the right deal." However, the seller may be thinking, "He's buying my frames right now." You may say, "I want to buy your frames," thinking, "I would like to buy but I may not," while the seller is hearing, "He's going to buy my frames."
I hope we can all agree that telling someone that you are definitely going to buy their frame(s) and not doing so is wrong (Chris, I could not tell from your posts that you thought this way). An agreement to buy, even on the internet, is a legally binding contract. Not sending money after agreeing to buy is not only morally but legally wrong, even if no one was materially "ripped off."
