On a friend's recommendation, I went to drugstore.com and discovered they have a subsection of their website devoted to FSA shopping. I've just blown $60 on contact lens solution, ear drops and condoms.
I've also made an appointment with my optometrist for December 5 to obtain a new prescription for contact lenses. I should be able to blow another $100-150 on the consultation, and about that much again on the lenses.
Whatever is left over will used on something --I don't know what yet-- before December 31.
