I just got back from a trip to Costco to use up the rest of our Healthcare FSA for the year. If you put money into it, you only have a week left to buy things to “use it or lose it”.
Some suggestions that qualify:
Contact Lense Solution
Extra Contacts or Eyeglasses (at Costco you pay when you order.)
Headache or Flu/Cold medicine (I didn’t get a flu shot this year, like many.)
First Aid Kits, Bandages, Hydrogen Peroxide, etc.
Need more ideas? Drugstore.com even has an “FSA” area that you can browse. I’d be careful to print out the right screen to get an official receipt your FSA administrator will accept.
