Eu Natural tip
You don't need to finish or even open the bottles to get a refund within the window - Eu Natural explicitly accepts empty bottles back, which is unusually generous for a supplement brand.
FLEX tip
All sales are final by default, but FLEX will still make exceptions for damaged or defective items if you email support right away - it's just not a published, guaranteed return right.
