you do find the odd bargains here and there, but too many people have cottoned on to things like key words and you'll be looking for something and all of a sudden all you will have for page after page is some tat that has nothing to do with it

and i can second the thing about wheels showing up in a listing, as well as wiper blades and shit like that when you are searching for a switch or whatever

that said, once i have a good source for something i'll buy time and again, i tend to stick to that once source, regardless of who else may have it for 10p less, but that doesn't mean to say i spend 5 hours looking for a bargain that will save me 10p, if i cna't find something fairly easily i just don't bother looking for it again
