Do not trust this company for special offers. They use bait and switch, change their website to conceal 48 hour dispatch guarantee after order then email you 4 days later to say the frames arrived damaged (hello, I ordered 3 pairs and got the same email for all orders) and you will have to choose something else. Despite claiming to be an NZ business I got a call from the UK after making noise. Money was taken from my account straightaway but they say it takes up to 5 days for a refund. Totally untrustworthy
