MyHeritageDNA is running a sale in Ireland, the UK and the USA. (There may be offers in other parts of the world, too, but I can't find access details of them as I can't by-pass the geo locators, grrrr!)
The price of the MyHeritage DNA testing kit is €69 | £69 | US$69, reduced from €75 | £75 | US$75, respectively.
In each case, shipping is free if you order two or more kits.
The sale offer runs until Monday 20 August.
