Wow - I would be seriously aggravated if the backorder was strictly color based for something that likely doesn’t even make a difference. Blue vs Grey on a transparent infusion set? Would have been nice for them to let you know and ask if the other color would work.
In any event it is great you received your supplies.
Are you on a 30-day reorder program or a 90-day? 90-day is nice you have to do it less often but 30-day gives you the option to try different things out more frequently. Advantages either way.
