One thing to remember if your doing some shopping around online is that make sure you are comparing apples to apples, for example a lot of these places advertise any cover for $350 shipped to your door but that may only be a 1lb foam, no vapor barrier, 1 year limited warranty, 3" to 2" taper whereas your factory cover may be 2lb foam, vapor barrier, 2 year warranty, 4" to 2" taper, etc. etc. so if you "upgrade" these $350 base price covers to equal specs your at the $500 mark not saving a penny, plus some of these places take 3-5 weeks (unless you pay to expedite) where your local dealer may have one in stock....I have no knowledge of the specs on Jacuzzi covers so these are some things you'll need to look into...good luck
