Fitness Repair Parts Ridiculous return policy Internet

Beware! Fitness Repair Parts has an absurdly limited policy on returning electronic parts.  It was a shame, too, because I had some positive experiences with them in the past, but this year, they sold me a $500 refurbished console for an elliptical.  The first one worked, but imperfectly, so I returned it. The second one worked for a month then konked out completely.  Oh wait!  You only have 21 days!  21 days?  For a $500 piece of equipement?  Ok, what about sending me back the one I just returned?  At least it worked most of the time. No.  “It will already have been sent to be refurbished.”  And re-sold to some other sucker for another $500? When it will hold together for maybe another month.  The policy is stated, but it is not a reasonable policy.
