Just wanted to know that if I order 5 packs of 3’s, does it charge $5 shipping for each 3 pack? or it will be $5 for the entire 5 packs?
order instructions are not clear!
how do i order 3-pack & how much total mailing for all three? mail answer to gerry_villaroman@yahoo.come
light switches should be made from oxygen free copper so that they last longer,*-
the best smoke alarms are the ones that use photoelectric sensors`*:
the light switch we have at home are made by Omron and they last for a long long time”,’
