Hi! I have a brand new, never been used PIS with battery pack for sale. I purchased it brand new and as an adoptive Mama my intention was to bring in a milk supply and breast feed. Well, to make a long and drawn out story shorter, after successfully taking the med's and bringing in a supply, I decided not to go to the pumping stage because of recurrent migraine headaches for which the med's are not suitable for babes. So, I scrapped the idea and never did use the PIS. I purchased it for $249.00, and I am asking $180.00 not including shipping. If you are interested, please e-mail me at [email]Mara.fazekas2@verizon.net.[/email]
