A couple years ago, my employer began offering a FSA (Flexible Spending Arrangements) for healthcare expenses. Once they began offering this product, I had to do some research to decide whether it would be a good deal. I initially couldn't decide, because I didn't want money just sitting around not growing!While researching the FSA, I stumbled upon the HSA (Health Savings Account). I discovered that the HSA is a much better product. Despite this discovery, I still found that investing in a FSA was worth it for the Summit of Coin family (that may change toward the end of 2018).
