This is one of the best-reviewed vinyl pergolas you can buy for under $500.
Brad's Deals Editor Marisa,
This Arlmont Kingston 7' x 7' Vinyl Pergola drops from $599.99 to $439.99 at Wayfair. Shipping is free. This is the best deal we found on anything similar, and most pergolas from major retailers have additional shipping fees of $50-$100 on top of the regular price. It can be left up year-round, and comes with a 20-year limited warranty.
