White Glove Delivery - Available -

What is White Glove service?

Standard common carrier delivery options cover the cost of getting an item to your shipping address but our White Glove delivery service does that and more!

The White Glove agent will call to schedule a Call Before Delivery within a four hour window, which gives you the flexibility to work around your busy schedule and to prepare the space where your item will be placed. Upon delivery, trained professionals will unload your large item from the truck, bring it into the room of choice, unpack the item and remove all packaging debris from the premises.

Please note that White Glove delivery will typically add 5 - 7 business days to your order's transit, and only includes 30 minutes of on-site time. If on-site time beyond 30 minutes is required, you may be responsible for additional fees. While the agents will bring the items into the location of your choice, this service does not include set-up of the items being delivered, such as installation of casters, shelves, or other accessories. Small items will not be unpackaged individually; they will be set in place and debris and packaging material will not be removed.

Grilling Hamburgers with the Winston Cvap

Grilling Hamburgers with the Winston Cvap

Are long ticket times putting you in the weeds? Imagine serving a hot, juicy burger in 3 minutes or less! This time lapse video shows that in the time it takes to cook one burger from a frozen patty, we can cook 3 Cvap stage burgers. The burger patty near the top of the screen is the frozen one while the others have been Cvap staged. The previously frozen patty is finally done and it looks torched. The 3 Cvap staged burgers are far juicier and more visually appealing. Turn the tables with Cvap staging and serve more covers in less time.
