Nice product
Thanks for the review Steve. We actually now offer customers the option to upgrade to a faster dispatch time if they so choose, along with our existing standard dispatch, depending on how quickly the items are needed. All products still include free next day delivery, but customers are able to select how fast they need them dispatching. I'm glad that you're pleased with the oak sill and hope to see you return sometime.
