When LETSBuzz was founded in 1995, members were told to estimate prices by starting off from the point of 1 Buzzard being roughly equivalent to 1 pound sterling.
Interestingly, Buzzard prices have remained more or less constant since then - there has been no general inflation. Hourly rates paid for work for the LETSBuzz system itself, however, have risen from 4B/hour to 6B/hour.
