Assuming you are referring to the popular car floor liner company, WeatherTech, deliveries generally take around 3-5 business days. However, this can obviously vary depending on a number of factors such as location and time of year (holidays etc.).
WeatherTech products are made in the USA, in Illinois specifically, and they have a huge range of products available for pretty much any vehicle imaginable. You can order directly from their website which is quick and easy to use. Payment is also straightforward as they accept all major credit cards.
Once you've placed your order, it will be processed and then shipped out via UPS or FedEx. You should receive a tracking number so that you can follow its progress. As mentioned earlier, most orders will arrive within 3-5 days but this is only an estimate.
Overall, ordering from WeatherTech is a very smooth process and delivery times are reasonable. Their products are high quality and definitely worth the wait!
