Thanks for sharing. That's a fantastic price. When I called Costco I was quoted a much higher price but I guess it all depends on location and timing.
I found an infusion company (Infuserve) in Florida that provides iv meds (balls), pharmacist/nurse on call 24 hours a day to answer questions and all supplies (saline, heparin, alcohol wipes, bandage change kit, gloves, etc.) for $187 per week. Shipping was approximately $52 and can be arranged once a month as opposed to once a week to save money. I realize this is much more than $179 per month but still much less than $700 per week.
Good luck to all!
