Signature is pricier than Canvas (and honestly I think I like Canvas a little better), but there are a couple of looks that have my eyes go all googly with Want (see below). Plus I don't think LL Bean is as free with their discounts and free shipping as Lands' End is, but they are offering a $10 gift card with a purchase of $50 or more.
I did check through retailmenot.com and it looks like there may be a couple of successful codes for free shipping out there (3018863 or 3020392). I can't vouch for them though, so can't guarantee if they'll work or not. No minimums or expiration date were provided.
Comes in Midnight and Vintage Rose ... I don't know which color I like better.
