@jprust A lot depends on how many exchanges a day you are doing. I do two a day, and use manual for my exchanges, not a machine. So, my monthly supply is a lot less than someone else. My bags come 5 to a box, 2000cc in each bag. If you use a cycler, it is (2) 10000cc bags to a box. Add in the caps, bandages for daily site change-out, antibacterial soap, hand sanitizer, and cleaners. A box of caps lasts me 3 weeks. And don't forget they advise to keep a couple weeks' extra on hand of all supplies. If you have a storage issue, many providers can arrange a twice-monthly delivery.

I would figure a regular pallet size of supplies each month, about 3-4 feet high. Your initial delivery is especially big, as various one-time components arrive. Remember, the delivery drivers are instructed to place the boxes of fluids where you tell them to. Are you using manual or a cycler? How many exchanges per day?
