Beware of Groupons deals!

Almost bought a cordless drill from Groupon, discounted from R1,700 to R900. Fortunately I checked my local hardware for a similar product and found the bigger more powerful model of the same brand for R170 less! Beware of these so called discounts and great specials, if you do your homework you will find a lot of these \deals"are highly inflated offering massive discounts that still work out more expensive than retail or online shops."""
