The match against the Bosnians, which Celtic won 2-1 to score a 5-2 aggregate victory, was free for season ticket holders, but every fan will have to cough up for the next round.
For the visit of Kalju, season ticket holders will be asked to pay £24 for an adult ticket, £13 for concessions and £8 for children.
For those needed to purchase via general sale it's £26, £14 and £9.
It prompted a response from fans on social media, many of whom were not happy with the pricing.

@Scoosh_1 said: "Definitely wont be going to this... honestly disgusted with the club charging for this fixture."
@mdcfc88 tweeted: "Ripping fans off again. Scrap the friendly no one wants and give us 2 qualifiers."
While @JamoMax85 added: "The friendly against Rennes was good value for money to be fair, only right that you offset that with a wee fleecing for the visit of the Estonian champions."
There were some fans who defended the club's prices.
