Final shipping options are a function of size, weight, and where the product ships from in relation to your location. Over 95% of all products ship from the US or Canada. All orders include free shipping within the continental US.
When ordering multiple products, you should expect each product to ship from different warehouses, arriving to you in different packages and at different times. When possible, ChristmasDJ ships products in one package.
Shipping times are slower due to the Covid-19 virus, therefore, you may encounter longer delays in receiving your package(s). For orders outside the United States, shipping prices may be higher and ship times delayed.
