I got my medela pump from a medical supply store (I'm in mn, the store is in woodbury - superior medical services). They sell replacement parts, accessories and nursing bras/tanks also. Since they're a medical supply retailer, all of those items can be purchased with HSA or can be submitted to FSA. They were so helpful with explaining the pros/cons of each bra and helping me to try them on. With how expensive they are I was pumped to be able to use my HSA to pay for all of it! I got some extra membranes and two bras!
