I doubt anyone was surprised by the news of price hike by Royal Mail from April this year. I have seen many retailers offering as low as £2.50 for orders upto a Kilo and it was good value for money. This will all change in few months and I can see many small retailers worrying about dip in sales with the price rise. Of course big boys like Amazon will absorb the rise and go on but small retailers will definitely be squeezed.
What are you planning to do ? Are you looking for alternatives ?
