Once upon a time I actually placed an order with LB so they got my info then. What I dislike most is you can't cant look at a specific type of pattern, say just knit hats, and to find anything you have to scroll through a lot of stuff that's not pertinent. A lot of their patterns show up on ravelry and that's how I first become aware of them. I wrote something about using one of their patterns once and got a code for *I think* $5 off on my order from them. Overall I think the site is poorly set up and finding what I want there is more likely to come from a ravelry link or a google hit.
I should never overestimate my basic arithmetic skills.
