Hey @IKEMAN91,
It looks like our Membership Services team was able to get back to you. I’m sharing their message below so others can find it helpful if they run into the same thing.
Unfortunately, we can’t use HSA cards for upgrading membership, purchases on membership via shop.whoop.com and join.whoop.com. A personal form of payment must be used when purchasing.
Once purchased, submit a claim through your HSA provider to manage the reimbursement process. If you have issues with the reimbursement process, contact your employer or provider. You can click here to know more about HSA/FSA eligibility.
