Lowes Rubbermaid Roughneck Storage Shed 5-ft x 6-ft $429; 5-ft x 4-ft $329

Been trying to find a deal on storage shed for the past several weeks but could not find any on this site. It is almost November, I did not want to wait any longer so I went to a local Lowes store to check if those smaller sheds would work. There I saw the 5′ x 6′ and 5′ x 4′ sheds are on sale thru 10/30/2018:
Save 18% on 5′ x 6′; or save 23% on 5′ x 4′; can combine with Lowes 10% moving coupon as well.
