My solar pool cover is beginning to disintergrate. We usually get about 2 seasons out of them (12 mil) so I went online to Amazon to buy a replacement. I paid $85 in March 2018 (not used until May that year) and was astounded to find the exact product - a 16 x 32 blue 12mil cover is now a whopping $169.00! I've been searching the internet and either they are out of stock or in that price range. Clearly a supply and demand issue, but just curious as to what has caused the tremendous price increase. Wondering if because of Covid-19 - are folks using their pools more and buying more covers? Any thoughts?
