Hello. I've been trying to find a size 2 yellow lunette and haven't been able to find one available. However I came to this site which has it. I checked out the prices and to my surprise the cups are less than $40 in my currency. Even free shipping (without tracking) Everywhere else lunettes are $70+. Thought "no way!". Are they really lunettes or cheaply made lunettes? (Like there are some issues with them). Why so cheap? I'm sceptical about trusting this site when it's $40 cheaper. But no where else sells Lucia (yellow) in size 2 at this price.
