$300 · Pool cover and roller mechanism

25 foot round solar covered pool cover and roller mechanism I paid a considerable amount for this pool cover that raises the temperature of your above ground pool by capturing the sun's heat and the roller mechanism that rolls it up in 2022, around a $1,000 from Pool Supplies Canada. We used it for one season but then our pool leaked and we have since gotten rid of the pool. I am asking $300 or best offer.
