Baby Pavilion made it easy to get my pump, extra supplies, and monthly bags. They have their own prescription form, but I didn't know that at the time I got my prescription. I used the Tricare West prescription form and uploaded it to Baby Pavilion and had no issues with it. They send monthly reminders for your milk storage bags reorder form, which is very fast to fill out, and shipping is reasonably fast. It did take a couple of weeks for my initial breast pump order to get verified and everything before they were able to ship it, but I think that is probably the case with all/most of the breast pump websites. Overall, happy with my choice to use baby pavilion and would recommend to others who have Tricare. Please note this is my experience as someone stationed in the US, however, and I cannot speak to its ease of use for someone stationed overseas.
