David Reid Electronics was a large chain of electronics hobby shops around New Zealand. They stocked a wide range of computers, including Commodore and Sinclair. Here is a brochure they printed for the ZX Spectrum.
Here's the Atari 800XL brochure to match the 600XL brochure I posted a few days ago. Also included is the accompanying letter from Monaco Distributors, the official Atari distributor for New Zealand - frustratingly undated, though the price list with it was dated Spring 1984.
