well i've been to warehouse cuz i living close by and i think that swf is one of the better ones. i've never order from them yet so i cant sya but i'll sya that there are plenty of people that are happy with them! besides swf, the only other site i'd buy from is the dr.'s site. but if your ordering today them by the time they get to you the trite levels should be lower so it more then likely would be ok! i'd wait to the levels were 0 but if there less then .25 then youll be ok!
