Please note that due to supply chain challenges on certain products lines we’re having to use more than one supplier, this may cause a slight variation in the products you receive from SMI. Non-stocked and special order items have a longer lead time, so when placing an order with multiple products the whole order will be dispatched once the non-stocked items arrive at our distribution centre.
