Can I still return it, and is it still under warranty?\u003c\/h4\u003e\n      \u003cp\u003eYes to both. Closeout just means we are selling through the last of this GLI inventory at a reduced price. Your \u003cstrong\u003e30-day return window\u003c\/strong\u003e is the same as on any other cover, and the cover carries the full \u003cstrong\u003e8-year limited, first year full\u003c\/strong\u003e warranty. The only catch is quantity: when a size sells out, we cannot restock it.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n    \u003cdiv class=\"glicla-faq-card\"\u003e\n      \u003ch4\u003eWhat is the difference between GLI Classic, Estate and Silver Premium?\u003c\/h4\u003e\n      \u003cp\u003eThey are the same idea in three weights. \u003cstrong\u003eClassic\u003c\/strong\u003e carries an 8-year warranty with 1 year full, \u003cstrong\u003eEstate\u003c\/strong\u003e steps up to 12 years with 2 years full, and \u003cstrong\u003eSilver Premium\u003c\/strong\u003e tops the range at 15 years with 3 years full. All three are solid polyethylene with Hold-Tite seams and brass grommets.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n    \u003cdiv class=\"glicla-faq-card\"\u003e\n      \u003ch4\u003eIs a solid winter cover the same as a safety cover?\u003c\/h4\u003e\n      \u003cp\u003eNo, and this is the one thing to get right. A winter cover is a tarp that floats on the water and keeps debris out. It is \u003cstrong\u003enot\u003c\/strong\u003e a barrier and will not support weight. A safety cover is anchored into the deck with springs and is built to the ASTM F1346 standard. If you need to keep children and pets out of the pool, buy a safety cover.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n  \u003c\/section\u003e\n  \n\n  \u003csection class=\"glicla-cta\"\u003e\n    \u003ch2\u003eGrab This Classic Cover Before It Is Gone\u003c\/h2\u003e\n    \u003cp\u003eAuthorized GLI dealer.
