Ok all a totally unrelated question but here goes. Question. When you shop online which do you prefer/more likely to go for A or B? The reality of free postage is that really it is just written into the product price, ebay is a prime example of this sort of thing. A: item for sale at £100 but has free postage B: item for sale at £94.99 but at checkout you get hit with the postage of £5.01. So your still paying £100 in the end.
