I'm not surprised someone wants to open a card shop, they're probably not being paid enough at UBS or Credit Suisse.     In a recent survey conducted by me, all cards in Northcross road emporiums cost ?7.50.     Cost Breakdown:     ?0.10 Materials, ie a small piece of thin card    ?0.20 Labour    ?0.05 Envelope Cost    ?0.05 Supply Chain    Total Cost ?0.40    Total Gross Margin 94.66%           Cards and taps, the 2 highest margin products around.     Just dont get me started on taps.
