Cooking.com will ship it out to you but you need to ensure that you order by a certain date for it to arrive in time for thanksgiving. So take note of their shipping dates so that the cake arrives in time.
They will only ship during business days so any orders placed on Friday or the weekend are not shipped until the next available business day.
This isn’t cheap and really you could probably make it yourself but what you are paying for here is the convenience of not having to cook it yourself. So it’s a big saving on your precious time especially around this busy season.
