welcomekrista!
first congrats on your choice! sometimes its hard to come to the realization that 'self' isnt cuttin it....i was like that too. broke dn in june and went to meetings and am now dn almost 53 lbs!
groups are great! weigh ins are private and talking is optional

as for $, you can pay weekly or purchase pkg's which save $. if you go to the ww site, and type in the zip, itll give you current pricing. good luck! and pm me if u wanna buddy up!
