Team Estrogen - narrower selection than they used to have (*sniff), but still have Shebeest (which is my favorite) - reasonable shipping, good service, and reasonable return policies
REI - Selection can vary widely (they do sometimes have Shebeest and other brands I like), but shipping is usually free and can be returned to a store; generous return policy
Terry - love or return it guarantee; shipping sometimes free if you sign up for their emails.
