Note about prices:
British prices were in pounds (£ ), shillings (s.) and pence (d.). Each shilling is 1/20th of a pound, and each penny is 1/12 of a shilling or 1/240th of a pound. To convert to pounds, count each shilling as 0.05 pounds and each penny as 0.00417 pounds. Three pounds, twelve shillings and six pence is therefore 3.625 pounds.
In July 1996 one pound was worth 2.12 Canadian or 1.55 US dollars.
