For transitlink guide, if in good as new condition, I will buy in at $1.50, add 3% to the original take in price per year.
Example:
Transitlink Guide 2001, good as new,
2009 - 2001 = 8
$1.50 x 3% = 5cents.
5 cents x 8 = 40 cents.
I will pay you $1.90.
If condition is not that good, I will buy in at $0.50, same 3% per year.
For bus tickets
CSS/TIBS = 10 cents per 2cm
SBS Tickets with bigger logo = 10 cents per 2cm
SBS Tickets with smaller logo = 10 cents per 1.5cm
SBS Transit and SMRT = 10 cents per 5cm
Thermal tickets = no value
