Found these guys advertising on my facebook (they're in the US of A), haven't used them so happy for anyone to give feedback if they have. Shipping might be expensive-ish, as I'm at work I didn't go through the process - again happy for people to note how much it is.
They give away 1,000 pairs per day, so if it's all done today then try again tomorrow (assumedly US time)
Interestingly they have another code on facebook (can't be used together), lens25 which gives 25% discount on the cost of lenses, AND (as per their website - http://www.firmoo.com/help-c-10.shtml):
"When the amount of your shopping cart exceeds $35, you will be entitled to free shipping. The free shipping service is available for customers from any countries… ",
so it might be cheaper to make your bill $35 with the 25% off and get a nice pair of glasses for $35 with delivery.
EDIT: just saw on their homepage they say free shipping is for over $60, so don't know which is true…
Price of postage would be nice. (I'm feeling lazy.)
It's probably around $10 like Clearly Contacts I reckon.
