Excerpt from the website of the festival organizers:

Prices for balloons will change in a big way:
- the desire to have something "such, well, not like everyone"
- jump your ideas from place to place with subsequent dismantling of the design - from 10%
- work in the moonlight (from 23.00 to 07.00) + 20% to the cost of the order
Installation works above 3m above the ground + 10% to the cost of the order
Temperature below +5 Celsius + 10% of the price of the order
by PRIM. During the frost, the designers below 40 degrees do not offer.

Well, and of course, the pricing will change immediately if:
Acquired in 5 days + 10%
Recovered in 3 days +20%
by OBU! It is today!! More than 100%"
