Disagreeing does nothing for my feelings, its about principles! The principle that you don't treat people like that, especially when they technically are doing you a favor! The favor being, coming to your house and paying you for your stuff that you no longer want or need. Albeit you as a buyer want said stuff, but most companies spend millions of dollars a year in advertising alone just to try and get people to do this, and what do most kijiji sellers pay $20 bucks if that and usually its nothing! If business' operated in such a way they would go under in no time at all, and arguably if you are selling something you are a business. Finally, the sheer fact that the first person to show up with cash gets the product baffles me, especially when someone tells them "consider it sold." Where as the graciousness and courtsey towards others gone in our society and when did a man's/women's word start to amount to nothing at all?!? Sure I can understand that if someone was wishy washy and said, "I might be able to make it, but i don't know," then fine the first-come-first-serve premise works, go for it! But for a seller to give a product away (aka sell it) in such a manner is not only greedy, lazy and as mentioned dishonest. This is not how I work when selling things online! I have always given ever interested party the opertunity to purchase whatever product I happen to be selling and I never lost a sale nor have I ever had any issues. Not to mention its not that hard, its really quit simple!
If you want to be a jerk about it go ahead thats your prerogative! But I won't work that way and I certainly won't be happy about it when it happens to me.
