At RGB Direct, we continually monitor our prices to keep ahead of our competitors. This takes time due to prices changing constantly and it is therefore impractical for us to always offer the best prices.
However, if you find the same product cheaper, supplied by a UK authorised dealer, brand new, boxed and in stock, we will endeavour to match or beat their price prior to purchase. This excludes any grey imports and online only retailers. Unfortunately we're unable to offer price matching for products purchased on finance or if you've used a discount code.
