Because all companies like to make more MONEY. That is why we (population) have to have this non-sensicle charge levied on an item. Accept the item but moan at them and say the delivery charge makes you reluctant to reccomend them to others. Send it to the customer relations manager and ASK for the charge to be REFUNDED. it worked for me when i got my PC tower, monitor etc.... GO ON, dont nod and do nothing... COMPLAIN about it and complain loudly!
ITs your money, say you want it back!
