Do I submit every recurring purchase for reimbursement, or can I send them all at once?Updated 5 days ago

Either works. You can submit each recurring purchase as it happens, or save them up and submit all at once. Two things to keep in mind. First, your order has to be dated on or after the date on your Letter of Medical Necessity to qualify (an LMN is valid for up to 12 months, and Flex will help you renew it after that). Second, if you're using an FSA, plan to submit your eligible purchases within your plan year, which is usually the calendar year, since FSA funds are typically "use it or lose it." Check your plan for the specific rules and requirements.
