Shipping upgrades only apply to the delivery timeline and do not modify the order processing timeline.
Rhino typically requires a 1-2 business day processing timeline for items listed as "In Stock". Please allow additional processing time for orders placed during a sale. This timeline does not apply to products listed as pre-order, back order or items with an extended processing time such as "Shipping in 1-2 weeks". They will ship as soon as items are available based on the shipping timeline given for that specific product. The delivery estimates will also be inaccurate for these products, as the estimates are based on "In Stock" shipping being available.
Your customs processing time frame is not included in the shipping timeline estimate.
