This is weird but ive found customers like.
No free shipping. Customer figures that somewhere they are paying for the delivery in the price of goods they feel ripped off, so I offer postage charge of $1 per item plus P+P shipping of $2.95 per order.
Customers think that ive arrange a good deal for delivery, in other words the true cost is being hidden in the overall price, customers just fail to realise.
We're both happy that way.
