Just ordered a top up on my disposable contact lenses from
www.netoptical.com.au
Very efficient, delivered two days after ordered, good communication from the company, good prices.
Don't forget though if you're buying online that you should still have an annual eye check, and here I can recommend Laubman and Pank in Tea Tree Plaza: helpful, not pushy and didn't seem to mind that I was going to buy my lenses elsewhere!
