There will be no problem at all when someone who is interested to buy something & decided that, after viewing, the item is not to his liking just tell the seller that he decides not to buy. I'm sure the seller will not mind that.
But if the buyer decides not to buy, gives unecesssary remarks & talks as though he knows alot of technical things (which in actual fact he knows nuts), then the seller have the reason to say that his time has been wasted (wasting time in letting the buyer come over to view the item & wasting time in the heated arguements).
Reefaholic, please continue using this forum to sell off your stuffs. One smart Alex maybe around to spoil your sales but just keep in mind that there are many more people who will be interested to buy your stuffs when they know exactly what you are selling. It's not important if FL casing is used to fit T5 or even MH lights. What most of us want is good quality of DIY.
Bwilly, if you know nuts about lightings, please do not voice out your arquements about it. Especially when your arquements could spoil other people's sales. You had spoil my previous sales with your "crude" remarks. If you have no interest in buying any items on sales, just skip the post let the seller finds his buyer peacefully. Do not put damaging remarks. The seller might be in deep finacial difficulties & he need some cash badly through his sales. With your kinds of remarks, you are "robbing" away his potential extra cash.
AT, I am making an "official" complain against Bwilly's behaviour. His behaviour is not welcomed in our community-based forums.
