I live in Jersey and have dealt with winter covers for a while, everything Mdragger88 said is spot on!
I leave some water on the pool cover to keep it weighted and it works. I have used the plastic wrap a few times but I haven't perfected the seal. We actually bought a food service saran wrap (18" wide) to try it this past winter and we never got around to it. I have never bought clips but I would imagine they would work but plastic being plastic - I would think after a couple of years they would need replacement. I know they sell water bags, some people hang water jugs around the pool (I see an issue with this but I may be wrong). Having an inch or so on top of the cover works great, when the wind blows the side puffs up and the water brings it down. I have a spare sump pump that I keep for draining the cover, pool, hot tub that I start up and let it drain by gravity so I don't have to watch it.
I have had good luck with Arctic Armour winter covers, good luck being I get 3 years (maybe 4) out of them before I have to toss them. Delamination is not covered under their warranty. I have used their warranty once for a different issue and they were great. I order them through Home Depot now, the Blue Wave brand seems to be making Arctic Armour but I may be wrong. Just my opinion but they are affordable, I pay about $80 for a 24 foot round cover. I look at winter covers and solar covers as disposable.
