mo tackle on line is cheap but why do you want the cheapest.
I prefer the best service and they must have what i want.
If it is a couple of bucks dearer well so be it, that is better than more bucks in fuel trying to find it and then being disappointed.
Buying on line means you have to wait and can only go off a picture.
Tackle warehouse at coorparoo has most stuff and you can handle it, view it and buy it there and then.
Also jones tackle at chermside and the tackle shop at castledine can supply some great gear if you need it in a hurry.
